I saw the homespun in solid colors at HL and it is a slightly looser weave than the calico they have. I would guess that it would be good for rag quilts if used with the homespun plaids. The best way to find out how it will rag is to buy a small piece (1/4 yd?) of each and sew together making a sample rag quilt. That way, you will know how much each will rag and also how much each square will shrink. I think the calico will shrink less than the homespun because usually the weave is a little tighter and the threads are finer.
