For several years I have made and sold sports related items. I buy some of my fabric at my favorite LQS. They know what I do but we don't talk about it openly in the shop because they've been threatened by one of their distributors that if the shop knowingly sell fabric to someone who sells stuff with the licensed fabric, the distributor will stop supplying the licensed fabrics. It's illegal extortion and the shop knows it so to keep peace(and to keep the fabric in the shop) we just don't talk about it.
