thanks PghPat ! I get these free from friends of min who make draperies and such. I use them for LWR quilts. made 7 this year. I also joined the local quilt club and a gal had a pattern I thought I could manage as I am a beginner. I now have enough to make a fairly large quilt that could be good enough for a benefit quilt. I had to be choosy of the design and color if I wanted it to look good. ready to sew them together but fear washing will shrink everything. Will it? Do I wash in cold water? Help !
