We’re going to cheat. You could either do a lot of cutting and pressing or you can do it my way. But since you’re still reading, I’m assuming my way is your chosen path. Excellent!
Fold your fabric in half lengthwise, right sides facing.
Make sure your fabric measures 35″x17″. You may have to trim some fabric from the width to make it 17″.
Sew the bottom and the opened side closed. Turn the pillow case right side out.
Please note that my pins are at the 5 inch mark, this is where you will top stitch. Be sure to hold the fabric so that you don’t sew the pillowcase shut. 😉
And…you’re done! You can add decorative trim, a monogram or anything you’d like to personalize your pillowcase.
