A friend and co-worker is having surgery in a couple weeks. I am making a pillow case for a pillow she just bought. The size of the pillow is 16x22. I asked her the shape and she said it was flat. I haven't seen the pillow and will be giving her the case tomorrow. It will be a coordinating pillow to a quilt I made her a few years ago.
I am using a fleece for the pillow case. It is a very soft fleece and almost stretchy. Kind of like minky but furry and not knobby.
What size should I cut the fabric before sewing? One site said to add 2 inches to the side and 6 to the top and 4 inches for the hem. Will this be enough if I use a 1/2 inch seam?
