How to Sew a Lightweight Quilt: Two Quick and Easy Methods for Summer

I don’t know about your household, but our bedding needs to change significantly with each season. The thing I’ve learned is this: great bedding is all about layering opportunities. This tutorial will show you two very simple, informal ways to sew a lightweight quilt that will be perfect for the summer season. This is the perfect project for anyone looking to spruce up your child’s bedroom this summer or renovate a guest bedroom before having visitors over to stay.

Two Fun DIY Quilt Projects for the Summer Months

View in gallery

A word of warning, though: If you’re looking for instructions involving precision and perfection, I’d continue your search. Because this sewing tutorial isn’t that. This is a get-your-fabric-and-sew-the-quilt-now kind of tutorial. Because I’ve got five young kids all on summer break right now and, frankly, ain’t nobody got time for perfection. We’re in it for the hammocks and lemonade around here.

This tutorial will walk you through two quilt-sewing methods. The first one is the inside-out flip method. The second is the straight seam fold-edge. Let’s get to it.

View in gallery

Materials Needed (for one twin-size quilt, either method):

  • a – 2.5 yards of 45” cotton quilt fabric
  • b – 2.5 yards of 60” cotton quilt fabric
  • c – two ~11” wide strips, each 2.5 yards long
  • d – warm & natural batting by the yard, ~60”
  • coordinating thread
  • pins, safety pins, scissors, sewing machine

How to Sew a Lightweight Quilt: step by step guide

Method #1: Inside-Out Flip

View in gallery

This method involves sewing around the perimeter, turning the quilt right-sides-out, and sewing small stitch-points throughout the quilt to keep the batting in place.

View in gallery

Align the Long Edges

Begin by aligning the long edges (selvedge, if there’s selvedge on your 11” strips) of your Fabric A with one of your Fabric C strips. The right sides should face each other.

View in gallery

Sew Edges Together

Sew these edges together, one Fabric C strip on each long side of Fabric A.

View in gallery

Lay Fabric A Down Flat

Lay Fabric A down flat on a large working surface (ahem, or the floor), right side up.

View in gallery

Open Up the Fabric

Before you’re done with this side, you’ll need to open up the Fabric C seams.

View in gallery

This will be one side of your quilt. Already done. Congratulations, it’s coming along beautifully, isn’t it?

View in gallery

Take Your Piece of Fabric B

Take your piece of Fabric B (2.5 yards of 60” wide, or the equivalent of 45” pieced together like the first section).

View in gallery

Lay it, centered, directly on top of Fabric AC. The right sides should be touching. This is critical for this to work. Got it? The right sides face each other, and the wrong sides face outward. Smooth out all sides. Pull taut everywhere.

View in gallery

One more time: the right sides are together.

View in gallery

Begin to Create the Warm & Natural Batting

An easy way to get the size of warm & natural batting that you need is to lay it, sideways, on your quilt fabric pieces. The fold will run across the short length of your quilt. Line up batting end to one side of your quilt then cut the batting along the other side of your quilt.

View in gallery

Like so. Now open up the fold, and lay the batting, centered, on top of your quilt. You should be laying it on top of the wrong side of Fabric B.

View in gallery

Working with Your Quilt Sandwich

So your quilt sandwich, at this point, will look like this from the ground up: Fabric AC right-side-up, Fabric B right-side down, batting.

View in gallery

Pull all edges and corners taut, taking care that there are no wrinkles hiding out in the center of your quilt anywhere. Now pin every 8”-10” or so around the perimeter of your quilt at the point of the shortest piece of fabric/batting. Always check all three layers to make sure you’re catching the shortest layer.

View in gallery

Sometimes when you get to a corner, the shortest fabric will switch (as in, another fabric might be shorter all of a sudden).

View in gallery

Be sure to always find the shortest fabric, and pin to that length.

Preparing to Start Sewing

I promise that, when you start sewing, you’re going to want to line up the edges. But if you’ve pinned them correctly, you can trust the pins rather than the mismatched edges. (This method is meant to be a time-saver for people who don’t like to measure and cut and trim and all that. If you find that it stresses you out, however, you can trim the edges to align with each other before sewing. Whatever brings you summertime joy.)

View in gallery

Pins will wrap around the entire perimeter of your quilt.

Sew Around the Perimeter of your Quilt

Using the pins as your guide but also checking constantly, sew around the perimeter of your quilt. Be sure to catch the shortest fabric. Also, leave about 18”-24” open on one side.

View in gallery

It’s not hard to keep an eye on the shortest fabric when you’re sewing. Just a quick fold of the fabric every now and then, to keep your bearings. You might also be able to feel through the fabric, too.

View in gallery

In this case, I can feel both separate fabric edges through the batting and am using that as my main guide.

View in gallery

Leave an Opening in the Perimeter

As I mentioned, be sure to leave an 18”-24” opening in the perimeter.

View in gallery

Eliminate Some of the Bulk

Feel free to cut the corner fabrics in a triangle (don’t cut the corner seam itself), to eliminate some of the bulk that will happen when you turn the quilt right-sides-out.

View in gallery

Flip Your Quilt Right-Sides-Out

Flip the quilt right-sides-out, and poke out all corners to be square.

View in gallery

Here’s your quilt. Looking good, right? And so easy so far. You’re not far from being done, actually. We need to take care of that opening first thing.

View in gallery

Close Off the Opening

Fold the edges of the opening in and pin them in place. You have one of two options at this point: You can sew just the opening closed (hand-stitch with one of these seams if you’re fancy; Summertime Me is not), or you can sew the entire perimeter of the quilt to give it a sort of banded edge look.

View in gallery

I machine-sewed the perimeter. (Sorry about the lighting shift at my sewing machine in these photos.)

View in gallery

The Final Stitches

With the entire perimeter finished off, the only thing you have left to do is make a few stitches in the body of your quilt to hold everything in place.

View in gallery

Lay your quilt flat again, and begin placing safety pins wherever you want them. Each safety pin marks a point where you will make a small stitch with your machine, about 1” long, to hold things together.

View in gallery

Add the Finishing Touch

When you have your safety pins in place for the entire body of the quilt, it’s time to sew them.

View in gallery

Place your quilt into your machine at the point of one of your safety pins. Make a 1” stitch line, reversing and stitching so there are three or four passes along the line.

View in gallery

I found it easiest to not cut my thread at each transition but instead just lift the pressure foot and find the next nearest safety pin. You can do what works best for you.

View in gallery

I’ll warn you: It’s easiest if you sew the pins in some sort of pattern so you can keep track of what you’ve already done and what safety pins still need stitches. Because it gets a whole lot of fabric bunched up with this method. Doable, for sure, and not too hard in reality. But a little messy.

View in gallery

Tidy Up Your Stitches

When you’re done, snip both the thread ends at each stitch.

View in gallery

Your stitches will look something like this. Peppered all over the quilt body, which means your quilt is now finished.

A Fun Reversible Inside-Out Fold Quilt

This is what your reversible inside-out fold quilt looks like. I love the reversible option here, with cute coordinating/contrasting fabrics.

View in gallery

The little 1” stitches all over your quilt are hardly noticeable, especially on a busy print.

View in gallery

Even on a more straightforward fabric, the small stitches are inconspicuous.

View in gallery

The Finished Product

The bottom bunk bed here shows the inside-out flip method, with the small 1” stitch points.

View in gallery

The quilt itself is extremely lightweight because you have to use relatively lightweight batting in order to flip it inside-out most successfully.

View in gallery

I really like the casual vibe of the stitch points. My daughter will probably flip it to the more flowery side, but I wanted to be able to show photos of what this one looks like.

Method #2: Straight Seam Fold-Edge

View in gallery

This method involves sewing five seams long the quilt body length, then folding over the edges and sewing them up. There is no flipping of the quilt involved.

View in gallery

Attach your Fabric C strips to Fabric A sides

Begin by attaching your Fabric C strips to Fabric A sides, lengthwise. Place right-side down on a large working surface (aka, the floor).

View in gallery

Lay Your Batting Flat on Top

Lay your batting (cut in the same way as shown in Method 1) flat on top of the wrong side of your Fabric AC, then lay your Fabric B piece on top of that with the right side facing up. In other words, your two fabric pieces should have the right sides facing outward, with the batting sandwiched in the middle against the two wrong sides.

View in gallery

Center All Pieces and Pin Your Quilt Body

Center all pieces, then smooth everything out. Pin along the very center, lengthwise, of your quilt body. Your pins need to be precisely aligned because these will guide your center seam, which will guide everything else.

View in gallery

Sew Your Straight Center Seam

Placing your needle about 3” from the shortest fabric edge, sew your straight center seam lengthwise through the body of your quilt.

View in gallery

Stop your seam about 3” before the end of your shortest fabric edge.

View in gallery

Smooth Your Fabric and Pull Everything Taut

Lay your fabric out flat again. Smooth and pull everything taut. Use a ruler to plant your pins a specific distance from the center line (example used 12”, although I’d recommend 10” for a more centered look).

View in gallery

Pin Placement

Place pins every 6”-8”, using your ruler with each pin placement. Remember, you’ll be using the center of your pins to sew your straight seam, so be precise with their placement. (In this instance, precision doesn’t take any more time or effort than non-precision, if you’re using a ruler anyway. And it’ll make things so much nicer and easier in the long run. Your Summer Self will approve.)

Sew the Seams

Sew the seam, directly down the center of each pin.

View in gallery

Repeat for all seams, for a total of five seams (including the center).

View in gallery

Cut Around the Edges

Lay your quilt out flat, pull everything taut and smooth, then cut around the edges at the shortest fabric edge.

View in gallery

Cut around the entire perimeter so that everything lines up. In this method, it’s important to line everything up so you can more easily fold in the edges and sew them.

View in gallery

Remember how you left about 3” from each short edge when you were sewing your five long seams? That will be important now.

View in gallery

Create a Folded Hem-type Edge

Begin by folding up your bottom fabric (plus batting, or you can choose to group the batting with the top fabric. Doesn’t really matter) to create a folded hem-type edge.

View in gallery

Fold your Top Fabric

Next, fold your top fabric (plus batting, unless you did batting with the bottom fabric) down so the folded edge aligns evenly with the bottom folded edge.

View in gallery

Pin or Iron in Place

Pin in place. Probably some people would recommend ironing this into place and pinning all the way around. I don’t roll that way right now; I pinned several feet to get a feel for it, but then I decided I could sew the rest by feel. Feel free to do what brings you joy.

View in gallery

This is what your new folded “edge” will look like before you sew. Pretty, isn’t it?

View in gallery

Ooh, I need to mention corners. Corners aren’t too tricky, but they should be done with care. (Pin these.) Begin by folding the bottom fabric (+batting?) down by a triangle.

View in gallery

Create a Finished Corner

Then fold the two sides in, to create a finished corner. Pin in place.

View in gallery

Repeat the process, only with folding under, on the top fabric.

View in gallery

The goal is to have the two corner points align, with no raw edges showing.

View in gallery

Start Sewing the Perimeter

Now start sewing the perimeter where you’ve pinned. I recommend starting about 10” after a corner; the corners can be used to prettily make up any differences that may occur during sewing the sides.

View in gallery

As you approach a corner, take care to keep everything aligned the way you’ve pinned it.

View in gallery

Sewing the Corners

Sew up to the corner, then keep your needle in the “down” position. Lift your pressure foot and carefully spin your entire quilt fabric 90 degrees. Drop the pressure foot and begin sewing again. This keeps a precise corner seam at your, well, corner.

View in gallery

These corners may turn out perfectly. They also may turn out a little slightly rounded, or maybe even with a three-way angle. Embrace the crisp corner you’ve sewn, and then try to keep all of them looking similar.

View in gallery

The Finished Seam

This is what your straight seam fold-edge quilt will look like when it’s all complete.

View in gallery

Depending (again) on the busy-ness of your print, the seam may be more or less obvious than this. But even if it’s obvious, it’s a straight seam running lengthwise along your quilt body, so it’s no big deal if it’s visible. It’s crisp, orderly, and keeps everything in line. I like the simplicity of this method, lots and lots.

The Finished Product – A Quick and Easy Quilt that Looks Just Like a Regular Quilt

This is what the straight seam fold-edge method quilt looks like on a bed. Just like a regular quilt, right? Who can tell it only took an hour or two to make?

View in gallery

I happen to really like the straight seams, even amidst a more abstract pattern.

Choose Any Color or Pattern You Like For Your Quilt

And, because we chose contrasting fabrics for each face of the quilt, it’s of course reversible. You can go more subtle/neutral with the chambray pinstripe, or you can be modern and girly with the abstract floral.

View in gallery

I love the way these lightweight summer quilts turned out; they are simple, fast, and fun. I can see this as a great way to make a quick blanket that would be perfect for a picnic, too.

I hope you enjoy your DIY reversible summer quilts… almost as much as you enjoy your summer itself. Summer is a great time to do a DIY project, and your whole family will benefit from these quick and easy lightweight quilts. We love the way they look on the bunk beds in this project, and they are the ideal way to spruce up a guest room in your home. The best thing about a lightweight quilt sewing project like this is that you can completely customize the quilt to fit your home décor. Go for a subtle color scheme or for something a little bolder and brighter. Whatever fabric you go for, I’m sure you’ll wow your family with their new lightweight quilts for the summer season this year.

Happy DIYing!
