There are a lot of *beautiful* gently used pillow cases out there... unfortunately, when you buy used you can never guarantee a matched pair for your bed. But I pick the pillow cases up every so often anyhow, with this dress in mind. And the pattern is seriously so simple, that it could easily be a first sewing project.
Step 1: Materials you need:
1 standard sized pillow case with a decorative edge or a great fabric
1 package 1/2 or 1/4 inch coordinating bias tape
a sewing machine
a shirt (for a pattern... will not be cut up!)
