Sew Envelope Pillowcase With French Seam

Posted on Last updated:

Hello November! It has been a while since I’ve posted something for you to craft. So today, I’m back with a sewing project on an envelope pillowcase! I’ve got a fairly good reason for my absence. As December is approaching, I’ve been diligently working on festive craft patterns for Christmas! Do stay tuned for that in future posts.

French Seam Envelope Pillowcase

Now back to the topic of the day: Envelope Pillowcase with French Seam

Pillowcases were one of my first few sewing projects when I was younger. I actually learned this technique from my mom when I was around ten years old, and I found it very easy to sew. This beginner-level project is not only simple to start with, but it also requires minimum time to complete. If you have a short 30 minutes out of your busy schedule, or if you just want something easy to wind down your day with, scroll down to see the free tutorial and pattern! Or, watch a short video below to learn to sew an Envelope Pillowcase With French Seam in less than 10 minutes.

Closure Finish: Envelope Style

While the traditional pillowcases have an open end that exposes one side of the pillow, pillowcases with an envelope closure at the end are made to be properly inserted into the pillow for a tidier outlook. The envelope flap allows the pillow to be tucked in and prevents it from sliding out when you sleep.

Here is a better look at the overlapped pillowcase with my Origin Superior Coolmax® Latex Pillow. The envelope flap wraps around the pillow perfectly so that it wouldn’t slip out whenever you use it.

As you can see above, the flap of my pillowcase is measured at 6”, but you can make it into a deeper flap at 9” by simply adding some length to the long side of the fabric cut-out accordingly. The materials and tools I used include; 1 yard (36″) of fabric with 44″ width for a standard pillow, quilter’s ruler, cutting mat roller cutter, sewing machine, threads, pins, and iron. However, if you don’t have those fancy tools, worry not. You can just use a pencil and ruler to draw the lines, and scissors to cut out the fabrics instead.

Seam Finish: French Seam

Ooh la la, doesn’t French seam sound like a fancy word? It is a method for hiding and wrapping rough visible edges into the seam allowance for a neat finish. The end product provides a clean and professional look. No serger is needed to overlock the raw edges.

As an accompaniment, the envelope closure further tucks the already-neat seam finish away from the opening. Love these combinations to the bit!

Fabric Amount Vs Size Of Pillow

If you’re planning on making this pillowcase with flap for other pillow sizes, just follow the below measurements of fabric requirement:-

Standard Pillow: 1 yard

Queen Pillow: 1 1/4 yards

King Pillow: 1 1/2 yards

Body Pillow: 2 yards

Note: The width of the fabric must be at lest 44″ wide.

Try This On Your Next Sewing Project

Get creative and increase the level of difficulty of your next envelope pillowcases by adding different fabrics for a distinct design. All you need to do is use a “flat felled seam” to join the strips of fabric. Flat Felled Seam is very similar to the French seam, it hides and wraps the raw edges at the seam allowance.

Learn How to Sew an Envelope Pillowcase with French Seam in less than 10 minutes. Watch the video tutorial if you like to view how to sew it in action. Read the following instruction with pictures if you prefer to save it for the future.

Quick and Easy way to sew an Envelope Pillowcase that makes the pillow stay tuck and inside the pillowcase. Using the same method to sew 4 most commonly use pillow sizes, fabric cut-out sizes were given to make your sewing process faster without the hassle to measure and calculate.

With a french seam finish, the raw edges are wrapped and hidden in the seam allowance. It is neat and looks professional without the need for a serger.

Materials

Cotton fabric of 44" width

  • Standard Pillow, 1 yard
  • Queen Pillow, 1 1/4 yards
  • King Pillow,  1 1/2 yards
  • Body Pillow, 2 yards

Tools

  • Quilter's cutting tools or seamstress's cutting tools

Instructions

  1. For a standard pillow size, cut your fabric to 42" wide & 36" long, 36" is along the selvage of the fabric. At the side of 42", make a straight cut of 6 1/2" long at the middle of the width, then cut out a 21" wide (half the width) x 6" long rectangle, scrap it. Now, your fabric should look like half of the fabric width is 6" longer than the other half, and, with an extra 1/2" snip in between them (5-Fig), that's for hemming purpose. This extra 6" length is the flap of the envelope Refer to 1-Fig to Fig-4 below for the cut-out shape and measurements for different sizes of pillows.
  2. At both edges of the pillowcase and envelope flap, press over 1/4", turn the edge over 1/4" again, and press well. You may use a finger press method if you prefer to do the press without heating up an iron. (6-Fig)
  3. Stitch both hems on the 21" width. (7-Fig)
  4. Fold the pillowcase with the wrong side together and sew with 1/4" seam allowance. (8-Fig & 9-Fig)
  5. Trim the raw edges if it frays excessively and clip both corners to reduce the bulk when the pillowcase is turned right side in. (10-Fig & 11-Fig)
  6. Turn pillowcase right side in and press the seam open from the wrong side. Align the seam and press again. Fold the raw edges of the envelope flap along (1/4") and press well. (12- Fig & 13- Fig)
  7. Fold the envelope flap over, align and pin. Sew with 3/8" seam allowance. At the edges of the envelope flap, backstitching to enhance the strength of the stitches so that the thread won't snap off easily in the future. Sew a straight line along the middle of the seam allowance of the envelope flap to stitch the raw edge in place. (14-Fig & 15-Fig)
  8. Turn the pillowcase right side out, make sure the corners are turned nicely. Slip in your pillow and tuck it nicely in the envelope closure.

Notes

I used quilt fabric because it is what I have the most in my fabric collection. You can use other grades or materials of fabrics, for example, comb cotton fabric, fabric with higher thread count, or even satin or silk. However, I don't encourage beginners to sew the pillowcase from satin and silk. Satin and silk are slippery and are quite difficult to handle.

If you are sewing this pillowcase for a customized size of pillows, please add a seam allowance 5/8" to your fabric on top of an additional 1" min for a loose-fitting case.

Hi there! Thank you for this tutorial, I'm using it to make my first-ever silk pillowcase! I have a quick question: the pillow I want to sew for is smaller in size than a standard pillow. It is 22" in width, 13" in length, and 3" in height. Using your example here, I'm trying to figure out the seam allowances but I can't quite work it out! Would you be able to let me know what your seam allowances in your diagram are? Thank you.

Good question, Karen, with the first sew of 1/4" and second sew of 3/8", the total seam allowance is 5/8". I will add this info into the pattern. Thanks for bringing up this question.
