Reading about batting not holding up makes me wonder about the fabric. I've read many comments about washing or not washing fabric first. Could anyone share some "happenings" about what has happened to quilts that the fabric wasn't prewashed and also if the fabric was bought at a store other than a quilt store. In my quilting group, some absolutely will use nothing but quilting store fabric, others use whatever they can find. I have done both or even combined quilt store fabric with fabric from box stores. Also - when you use a jelly roll or any other small pre-cuts that really can't be prewashed, how will they stand up - have any of you had good, bad or ugly results? Thanks for sharing.
