Thank you all.
The ruffle or the prairie points would be great, I had not thought of that.
How about putting the zipper off center on the back? Maybe a 2" strip to one side of the zipper. Then you can still add your binding
Sorry, I'm not sure if I understand what you say. For putting the zipper off center I have to cut the panel which is already quilted... or I am wrong?
The panel is quilted and trimmed to the size I needed to become the back of the pillow cover. It's just for that reason that I'm asking for help; I don't want to cut the panel...
