I have a parasol frame I would like to cover (got it in an antique store years ago), but it is a very strange frame. It has 5 sets of "double" ribs...five coming from the part you push up, which then branch into two separate ribs each going out to the ends. I've never seen anything like this, and can't seem to find another one like it on the Internet. I'm not really sure how to go about covering it, since it didn't have the original fabric on it and I have no idea how it would go on with those double ribs.
