I bought one yard of purple just to try it out. I do not remember any raveling with it. I seldom pre wash but did with this because it was such a dark color. I don't think it ran much but I honestly do not remember.
I try to use the best fabric I have for a QOV. I may use lesser quality in a charity project. We support many different charities through a group I belong to including local Vets. The Vets get my best (usually bought on sale) but name brand quilting cottons. I buy through Whittles and Thousands Of Bolts. I void Marcus as I have gotten thin fabric from them.
