I'm getting ready to start my down top quilt project and am stuck prior to putting scissors to fabric. I am 5'7" and am making a quilt with snaps and a drawstring foot box. I made a Rayway quilt several years Ago and it was slightly too small. I don't recall the dimensions. I want to avoid that problem again. What length would you recommended for my height? How much will I lose with the drawstring foot box?
