My backing is too small and I don't have any more left. How can make my backing large enough?
What I do when the backing is too small: Add any leftover blocks and put them in the middle of the fabric; add strips of leftover fabrics; print a photo of the person you will be giving it to (On pre-treated fabrics), or yourself; Make some blocks using your left-over fabrics and add them to the middle of the back; and if you don't have any left-over fabrics or blocks, use the backing as a guide for colors and make some blocks with the different colors with the same pattern you used on the front of the quilt. Does this help?
