You might make small, take-a-long blankies out of your squares to "practice". I have seen them pieced with alternating cotton squares, and backed with all minkee. It is slippery, but makes a wonderfully soft and cuddly backing and edging for baby quilts. I used cotton thread to piece and quilt with it as a backing on my GS's cotton log cabin baby quilt, and one other crib quilt I made. Am still using up the scraps on baby toys, but I think I will cut some squares!! I have also embroidered on it with no problems. Pin, pin, pin is good advice!
