My mother in law was a fantastic quilter. Picked out beautiful color combinations, excellent piecing; however, she bought the cheapest fabric she could find. Didn't matter if they were 100% cotton or whatever. We are paying for that now. It is such a shame to see these beautiful quilts fall apart at the seams because they fray so easily. My quilting is no where near the quality of hers, but I do make sure that it is 100% cotton and the best quality I can afford, even for baby quilts - they are washed alot more than bed quilts.
