some people have complained about the pinked edges on on precut, but if you tend to prewash your fabrics it makes it tons better! they do not ravel/fray. the complaints come from people feeling they are being (shorted) but i bet if you take a charm cut straight, and a charm pinked, wash them both, the one pinked is going to come out larger, because it will not fray. you may need to use a scant 1/4" instead of a full 1/4".
