Simple DIY Envelope Pillow Cover – Fast, Easy & Beginner-Friendly

For this tutorial, I made a 16×16 inch envelope-style pillow cover, but you can adjust the measurements to fit any throw pillow you have lying around. That’s the beauty of sewing your own pillow covers—total customization! You can pick the fabric, the size, and the vibe. Want to switch out covers for every season? This method makes it so easy to do that without breaking the bank.

A few notes before we get started:

I used 100% cotton fabric for my cover. I didn’t pre-wash it—gasp!—but I gave it a good steam press before cutting, which works fine for projects like this. Sometimes I skip pre-washing when I know a little shrinkage won’t be a big deal. In fact, a slightly snugger fit can make your pillow look even better!

My finished pillow cover ended up exactly the same size as my pillow insert—16 by 16 inches—which gives it a nice, tight fit. I personally prefer my pillow covers to look clean and crisp instead of baggy or loose.

Why you’ll love this easy DIY pillow cover project:

• You can sew a custom envelope pillow cover in under 15 minutes.
• No zipper, no buttonholes, just simple straight stitching.

How to Make an Envelope Pillow Cover – Step-by-Step

Ready to sew? Let’s dive right in and make a cute, custom pillow cover you’ll be proud of—even if you’ve never sewn anything before.

Step 1: Measure Your Pillow Insert

First things first—grab your pillow insert and measure it from seam to seam. Mine is 16 inches by 16 inches. We’re going to cut our fabric just a little bigger to account for seam allowances.

For a 16×16 pillow, you’ll need:

• One front piece: cut it at 17 x 17 inches (that’s 1 inch extra for seam allowance—easy!)
• Two back pieces: each should be 17 inches wide and 11.5 inches tall

Now you’re probably thinking… “Why 11.5 inches? That’s such a random number!”

If you want a little extra overlap (maybe your pillow’s extra fluffy or you like a more hidden back), go ahead and cut your back pieces a bit taller—like 17 x 12 inches or even 17 x 13 inches.

Check the Math (Don’t Worry, It’s Easy!)

Let’s quickly break it down:

• You’ve got two back pieces, each 11.5 inches tall
• Together, that gives you 23 inches of fabric for the back
• The front is 17 inches tall
• 23 – 17 = 6 inches extra on the back side

When we sew the pillow together with a 3/8-inch seam allowance all around, we’ll lose about 1 inch total in height. So that leaves 5 inches difference. We want about a 4-inch overlap to keep the pillow snugly inside, which means we have 1 inch extra to work with. Perfect—we’ll use that inch to hem the raw edges of the back pieces.

It’s really simple. Just take a good look at the pictures below—the back pieces need to overlap so the pillow stays in place!

Step 2: Hem the Back Edges

Let’s get those raw edges on the back panels looking nice and tidy. Take one of your back pieces and fold one long edge over by 1/4 inch. Press it with your iron to hold it in place. Then fold it over again by another 1/4 inch and pin it down. This double fold hides the raw edge and gives it a clean finish.

Do the same with the other back panel, then sew straight down each folded edge. Easy peasy—and it makes the back of your envelope pillow cover look polished and neat, just like the store-bought kind (but better, because you made it!).

Step 3: Assemble the Pillow Cover

Now for the fun part—putting everything together!

Lay your front fabric piece on a flat surface, right side facing up. Then place your two back pieces right side down, lining up all the edges. The back pieces will overlap in the middle—that’s what creates the envelope closure that holds your pillow in place.

Double-check that your corners line up nicely, and that the back pieces are overlapping like they should. Pin everything all the way around the edges to keep it secure.

Then sew all the way around with a 3/8-inch seam allowance. You’re almost there!

Step 4: Finish the Edges

To keep your pillow cover looking good wash after wash, it’s a good idea to finish the raw edges inside. If you have a serger, now’s the time to use it—just serge all the way around the seam.

No serger? No problem. Just switch your machine to a zig-zag stitch and sew along the edges. This will help prevent fraying and keep your cover looking great over time.

Step 5: Turn & Stuff!

Now flip your pillow cover right side out through the envelope opening. Use your fingers (or a blunt tool like a chopstick) to poke out the corners so they’re nice and crisp.

Stuff your pillow insert inside, fluff it up a bit, and admire your work—you just made a gorgeous DIY envelope pillow cover without a zipper in under 15 minutes!
