I will be running a Tea Towel Exchange for our Guild this year and the question of Rayon has come up. I have noticed that on several Exchanges 100% Rayon is excluded, ( which I aagree with) what about 50% Rayon and 50% cotton? I have suggested all the usual matierials, but am wondering if anyone has experience with this Rayon / Cotton mix or opinions about it's use.Several people in the Guild have asked about it and I've done some sampling for dish cloths, seems alright, but I don't want something that is going to be unsuitable in the long run. Your thoughts are much appreciated. Cathie
