If you can buy licensed fabrics and make stuff and sell it how do you get a fabric supplier to sell you that fabric for that reason?

Fabrics are manufactured to be made into "stuff". The "license" details are worked out between the owner of the design (for example, Disney or NFL) and the manufacturer of the fabric. If the fabric is available for purchase, you can do with it what you please.
