Everything I have read states that you may not share the pattern, but what you make from the pattern is your property to give or sell as you so desire. The pattern or book is copyrighted, but no one can copyright the product made from the pattern. The way I understand it, material is the same. You cannot sell a bolt of material without permission, but the moment you cut the material into pieces and make something, it is yours to do with as you please. I have not been able to find any evidence that a court upheld a copyright in favor of the copyright holder where the issue was a product made from the pattern, book or material.
