You Will NeedSmall fabric scraps.
Light weight muslin or any light weight non-stretchy fabric cut to 9 x 12 inches.
One piece of tulle cut to 11 x 14 inches.
While working on a project, I throw my fabric scraps in a box I have under my work table. After I have a big enough stash of scraps, I sort everything according to colour and store them in plastic bags.
