I have seen patterns that suggested you could use homespuns to make rag quilts. I have lots of red/greens and was thinking about making a Christmas quilt. Has anyone used homespun for rag quilts, and if so, how do they fray? How much of a seam allowance do I need and how far apart do I need to moake my clips for them to fray nicely? Also, are they cozy enough to do without batting? I think a cotton batting might be too heave...any thoughts?
