I'm still working on my purple/yellow quilt but have a question about the backing. I have a large flannel sheet that, color wise, would make a great backing for my quilt but I don't know how good it would work. Has anyone ever backed a cotton fronted quilt with flannel? I guess I'm concerned that the flannel might shrink more than the cotton whenever I wash it and also how well does flannel quilt. Any suggestions or ideas would be much appreciated.
