I have a crazy quilt top I got a a yard sale today. It is made with 18 inch squares.. She sewed crazy quilt pieces on to the 18 inch squares by hand. Then she attached the 18 inch squares together to make the top. Also sewn by hand. It seems to be made out of ties and silky material. The newspaper from the box is dated 1979. How should I finish this quilt? I think it needs a back and edges and how would you quilt it? How would you wash the quilt top? It is a bit musty smelling. It is very colorful.
