How To Sew a Pillowcase Using French Seams or a Serger / Easy Sewing Project
If you’re new to sewing, making a pillowcase is one of the best beginner projects you can start with. It’s simple, practical, and gives you the chance to practice straight seams, pressing, and finishing techniques.
In this tutorial, I’ll show you two easy methods for sewing a basic pillowcase:
A French seam method (great if you don’t have a serger)
A Serger method (fast and professional)
Both techniques create a clean, durable finish that holds up beautifully in the wash — no fraying edges here!
Supplies You’ll Need
- 1 yard fabric (standard-size pillowcase)
- Straight pins
- Seam gauge
- Scissors
- Rotary cutter, mat, and ruler (optional but helpful)
- Iron
- Sewing machine
- Safety pin (optional tip)
- Serger (for the serger method)
- Fabric suggestions:
- Quilting cotton (most common)
- Flannel
- Fleece
- Silky fabrics
Most woven fabrics come 43–44 inches wide, which works perfectly for this project.

Preparing Your Fabric
If using flannel or cotton, prewash first to prevent shrinkage.
1- Fold fabric in half (salvage edges together).
2- Trim off salvage edges (about ½”).
3- Square up the cut edges using your mat grid to a length of 36 inches.
You should now have a rectangle measuring:
36 x 43-44 inches
Helpful Tip:
Attach a safety pin to the salvage edge so you can easily remember which side is the pillowcase edge.
Pre-Fold the Cuff
Before sewing seams, prep the pillowcase opening:
Fold the wide edge down ½ inch — press.
Fold another 4 inches — press well.
Method 1: French Seam Pillowcase
French seams enclose all raw edges inside the seam — perfect if you don’t own a serger.
Step 1 – Sew First Seam
Place the fabric wrong sides together.
Keep the 2.1-inch folded down.
Pin along the side and the bottom.
(Optional) Insert a fabric tag into the side seam. (see video for more details).
Sew down the side and bottom, using a ¼ inch seam allowance. Backstitch at the beginning and end of the seam.
Step 2 – Turn & Press
Turn the pillowcase wrong side out.
Push out corners with a turning tool.
Roll seams flat with fingers.
Press well.
Step 3 – Sew Second Seam
Sew again along side and bottom using a ⅜ inch seam allowance.
This encloses all raw edges inside the seam.
Turn the right side out and press.
You’ll now see a beautifully finished interior — no fraying!
Step 4 – Finish the Cuff
Refold the pressed cuff.
Pin in place.
Topstitch along the folded edge.
Using an edge-stitch foot or a blind hem foot. This helps keep your seam perfectly straight.
Backstitch at the beginning and end.
Optional: Add trim, such as lace or rickrack, to the seam for decoration.
Method 2: Serger Pillowcase
This method is faster and great for batch sewing.
If using flannel or cotton, prewash first to prevent shrinkage.
Cut fabric to:
43” x 40” (Queen-size example)
Step 1 – Pre-Fold Cuff
Same as before:
Fold ½ inch — press
Fold 4 inches — press
Open the folds, leaving the ½ inch press
Step 2 – Sew Side Seam
Serger Corner Tip
Before serging the corner: Pre-cut the seam allowance just on the bottom corner, about ½ inches.
This allows you to pivot cleanly without bunching.
Place the fabric right sides together.
Align edges carefully — avoid twisting.
Pin in place.
Serge the side seam using a ½ inch seam allowance.
Step 3 – Enclose the Cuff Seam
Turn the pillowcase right-side facing out.
Refold the cuff along pressed lines so the serged seam is enclosed inside the fold — just like store-bought pillowcases.
Pin and press if needed.
Step 4 – Topstitch
Topstitch along the cuff edge using an edge foot or blind hem foot, for guidance.
(Optional: Add a fabric tag in the seam as shown in Method 1.)
Finished Pillowcase
You now have a beautifully finished pillowcase with:
Enclosed seams
Professional cuff
Optional decorative trim
Make a second one for a matching set — they sew up quickly!
Beginner Sewing Tips
Always square your fabric before cutting.
Press every step — it makes a huge difference.
Use French seams if you don’t own a serger.
Flannel makes especially cozy pillowcases.
