I received the DJ fabric that I ordered from eBAY. Exactly as shown in my previous post about it. I'll wash it in a bag as Klue suggested. I have some large mesh laundry bags that would work. I haven't yet received the 15 yds of background fabric that I ordered.
When I'm working with that large of amounts I have cut 1 yd pieces off to work with at a time (also don't want to wash 15 yards at a time in one piece!). I guess I'll do the same and hope that it doesn't eat up much in figuring yardage. Not too worried about it since it is a standard Kona color and I can get more. Won't be the same dye lot but, if I need it for borders and triangles or something like that then I don't think a slight difference will matter.
