I fuse mine with the lightest woven interfacing I can buy. Then I randomly lay them out after fusing and cutting them out. I cut the shirt just a bit bigger than I need then fuse it before cutting. Lay them out in a pleasing manner then sash some to make them fit or sew 2 or 3 together to make them fit the larger pieces. I don't match my sashing just sash and sew. This is clearas mud when I read it. But don't sweat it just go girl
