This is a pillowcase tutorial. I hope that I have explained it well, but if you have questions, please feel free to ask me in a comment or to e-mail me.
You will need 1 yard of fabric and 1 yard of coordinating fabric (this will be enough to make 2 coordinating - not matching - pillowcases). Decorative trim is optional (rick rack, accent fabric, ribbon, lace, etc).
Trim your fabric to 43 inches wide (ex: if it is 45" wide, you will trim 3" off the width) and 28" tall.
Trim your coordinating fabric to 43" wide and 8" tall.
With wrong sides together fold the coordinating fabric lengthwise and press it. (I embroidered my niece's name on it, see the right side - if you are going to do that do that now).
If you are adding a decorative trim (I did rick rack - does not show up for several pictures), baste it onto the main fabric now. The trim should be 43" long.
Now take your main fabric and roll it up fairly tight (if you added trim, start at the end without the trim). You are rolling it toward the wrong side of the fabric. Lay the coordinating fabric right side up, lay the main fabric roll right side down on top of the coordinating fabric, making sure to match raw edges.
See where the raw edges match up (with right sides together).
The roll should be quite smaller than the coordinating fabric. VERY IMPORTANT!
