I have used the Kaufman Kona fabric. I feel that it is a coarser weave than other cottons. It does seem to fray some but I haven't had it fray enough that it was a problem. I thought I used to get the Kaufman kona at JoANns and Hobby Lobby. The color selection wasn't good but they had some. Mone don't seem to carry it any more. The have Kona but it definately isn't Kaufman. I haven't used Moda.
