Help - how wide to make the boarder strip
I made a quilt top that measures 64" wide by 88" long. I want to make it at least a queen which I think is 86 X 93 and I'd like it to fit more like a bedspread rather than a quilt top. My question is: I have 4 yards of the fabric I'd like to use for a boarder but I don't know how wide to make the boarder strip or how many of those strips I would be able to get out of 4 yards. If I don't have enough of this fabric to make it long enough I can always but a smaller boarder on after this one but again how wide should the boarder strips be. I hope you understand what I'm asking because I'm at a total lost. Thank you
