I am working on a lap quilt now that I made of a jelly roll and will be backing with flannel. I did wash the flannel because I know how that shrinks but not the jelly roll. I figured I'd end up with a lot of fabric lost in the fringe. When I am completely done with the quilt, I'll throw it in the washer (with color catchers) and then in the dryer and pray for a good outcome!
