I was just thinking about this subject the other day. One of the first kind of 'quilt' projects I did back in the 70's was tying quilts. Sheets were a fast easy way to make bedspreads for the kids. Of course then you could actually find flat sheets separate from a set. The big plus is they can be washed and washed, drug around etc. and they wear forever. All of those quilts are nearly 40 years old and we are still using them. Now for the kind of quilts we make today when you are going to quilt they are harder to work with. Besides you now have the creative freedom to make the backing as fun as the top. If you want some great quilts for humanitarian projects and can find some bargain sheets; have a tie party and you can make some pretty fast. Don't ya just love playing with fabric (and of course buying it!)?
