I am making one of the scrap quilts from Quiltsville right now. Some of the fabrics I have are hideous but when cut in strips and sewn with others, the quilt is wonderful. I try to pick one dominate color (on this particular quilt it's red) and make sure that each block has at least one strip of red. When it's done, that dominate color gives some unity to the quilt. Also, we make prayer quilts at our church and they are usually approximately 50" x 60" quilts made from 5 1/4" squares and they are all made from scraps (because we try not to buy anything but muslin backing and the batting...most of the fabric is donated). Again, we try to pick a dominate color and once you put a border or two that kinda goes with the dominate color, they are quite beautiful. One lady I took lessons from told me to always put in one ugly fabric in my scrap quilts and I try to mind her instructions.
