Many of the kits are beautiful and of course the convenience is a terrific factor for those who don't like to cut out and want to get on with making the finished quilt (to say nothing of the precision cuts of the kit pieces). But as for myself, I haven't and wouldn't buy one because I diligently prewash every piece of fabric that goes into my quilts. If there are many different fabrics within a quilt kit, surely some will shrink differently from others or darker colors may bleed onto light. If there are kits that are guaranteed to be prewashed until there's no likelihood of uneven shrinkage or bleeding, it'd like to know where they're available.
