How to make a pillowcase

Making your own pillowcases can really transform the look of your bedding. It’s a great way to make sure your bed coordinates with the rest of your room without having to make a completely new set of bedding.

However, if you wanted to you could go the whole hog and learn how to make a duvet cover too.

In this easy tutorial, we’ll show you how to make a pillowcase with a flap. It’s really simple to follow and we’re sure that you’ll want to make pillowcases for every bed in your house.

We love the way these fabric inserts look like there’s one pillowcase inside another! We’ve gone for bold brights as our main casing; for a more subtle look, use a bright accent as the insert and a softer shade for the main case.

This project was first published in Simply Sewing Magazine. Simply Sewing is a beautiful magazine packed with patterns and practical tips for sewers.

How to make a pillowcase


You Will Need

  • Standard pillowcase (50x75cm (20x30in))
  • Contrast fabric, see instructions for sizing
  • Matching sewing thread

Total time:

Step 1

Turn your pillowcase inside out and undo the side seams. One of the short edges will already be hemmed and the other has a large pocket to slip your pillowcase in. You need to cut the pocket edge to meet up with the other edge but cut it 3cm longer for the hem. Turn over the edge by 1.5cm and 1.5cm again, then stitch down. The two ends of your pillowcase will now be the same length.

Step 2

Measure across the hemmed edge of your pillowcase and cut your lining fabric to this length and 46cm wide. On your lining fabric, turn both long edges over 1.5cm then 1.5cm again to the wrong side, press then stitch these hems into place.

Step 3

Fold the lining fabric in half lengthways with right sides together. With your pillowcase inside out, place it inside the folded lining fabric, making sure the two hemmed edges are all the way up inside the fold, aligning the side edges of the pillowcase and lining fabric. Stitch together down both side seams of the pillowcase, through all layers of pillowcase and lining fabric.

Step 4

Turn your finished pillowcase right sides out, with the lining fabric inside. When you put your pillow inside, make sure the lining fabric encases the end of the pillow.
