As far as prewashing the fabric- I only do it if the material is stiff or rough. (However, I always prewash red fabrics since red is a color that has a tendency to bleed.)
Well, Girlfriend- I am amazed you are tackling some pillowcases! How you do that with all the pain you're going through is commendable. You are absolutely the 'bee's knees', Sue!

Please take care of yourself and don't stress yourself out over this project! Hugs~Marcia
