I have never had any problems with multiple orders over several years. There is a box to check if ok to fold cloth. Shipping is more if sent on cardboard tube but no folds.
Recently ordered from Seattle Fabrics, and was completely unimpressed. Very slow to fill the order, and they packaged it badly so the fabric was damaged in transit. Caveat emptor.
Might also look for North Cloth's Norlam, a clear plastic laminate with a reinforcing weave.
