My border says it will be four inches wide but it"must have" a 3/4 inch stopper border that is darker than the dark constant (what a pain, I have several yards of the dark constant). I have some of the same that is solid rather than marbled so that will be darker. Anyway, I zippered mystery#9 into a project bag and am working on a Christmas tree skirt that I started a few years....hum... more than a few....years ago....wait, ok, this tree skirt is old enough to order a scotch rocks. But it will be finished today.
