What is the difference in us purchasing a bit of fabric to create with, then sell said creation and the person that buys a large chunk or bolt of fabric and re-sells it (starting price) at double or more the retail price? I know of at least one seller that is selling a NEW fabric, not OOP, at almost double the retail price. At least my item has some effort put into it other than cutting it.
There is another scenario which I have seen that I would absolutely side with the designer on. There is another seller that is copying one picture/item of the original fabric and enlarging it and selling such as a quilt block, or fabric block. I do not know that the fabrics being copied are protected, and I certainly don't know if she has an agreement with the manufacturers. Without certain knowledge of any agreements between her and the manufacturers, I'm not saying she IS doing anything wrong, I'm just saying that if she doesn't have an agreement, I would see that as a violation, IMHO.
