I like to make holiday-themed slipcovers and change them frequently. Therefore, for today’s post, I’ll be demonstrating how to sew an envelope pillow cover I made with a 4th of July theme. So grab your supplies, follow along with this simple tutorial, and learn how to sew an envelope pillow cover to make yourself a beautiful new throw pillow!

Envelope Pillow Cover Fabric and Sewing Supplies:

  • Pillow: You can use a pillow form from your local craft store, or you can use a throw pillow you already own.
  • Fabric: 1/2-1 yard depending on the size of your pillow
  • Scissors or rotary cutter
  • Cutting Mat
  • Pins
  • Sewing machine and thread
  • Iron

Envelope Pillow Cover Step 1:

First, you’ll need to cut your fabric. You will have one front piece and two back pieces. You’ll need to measure your pillow to determine what size to cut your fabric. The front piece of fabric is going to be the same size as the pillow. My pillow was 20 inches x 20 inches so I cut my front piece 20 inches X 20 inches.

Envelope Pillow Cover Step 2:

After that, we move to the back. To determine the size of your back pieces, you’ll need to do some very basic math. The width will stay the same as your pillow, and the length will be the width divided by 2 plus 3. (For example, mine would be 20 /2 = 10, 10+3= 13. So my back pieces are 20 inches x 13 inches.) You will need to cut two back pieces.

Next, we will be sewing the hem of the back flaps. To start, take your back pieces to the ironing board and press a small hem along one of the long sides of each back piece. To do this, simply fold under the edge 1/4 inch and press. Then fold it under another 1/4 inch, completely enclosing the raw edge, and press again. After that, do this for both back pieces.

Then sew the hem in place.

Envelope Pillow Cover Step 4:

Now, you’ll need to pin your back panels to the front panel. To do this, lay your front piece right side up on your mat. Next, lay one back piece right side down on top of it, lining up the edges. Next, lay the other back piece right side down on top of the front piece. The two back pieces should overlap. This will create an envelope-style opening for your pillow when you are finished. Then, pin along all four edges.

DIY Envelope Pillow Case Step 5:

Head to your sewing machine and sew along all four edges using a 1/2 inch seam allowance. Then, trim your corners to reduce bulk in the seam. Make sure not to cut into the stitching.

DIY Envelope Pillow Case Step 6:

Flip your pillow cover right side out. You can iron it if you wish to give it a crisp finish. Then simply insert your pillow and admire your work!
