In the law of products that are provided to make your own creations it is so that you buy the copyrighted necessary stuff .. example you buy Fabric to create your clothes the fabric is copyright protected , but as soon as you modefie the fabric and make a shirt ot of it the shirt and the fabric is under your copyright as you got only the material to create a new product.
