Do you realize what it costs to get an actual copyright?Copyrights are for printed material. Patents are for objects and what you are making is a patent. I had a copyright on my song I wrote and it at the time cost me 125.00. A patent costs even more. Then there is a thing called a license on things. That would be like taking a painting someone did, printing it out on fabric. I can show it, donate it to non profit, but I can't sell it legally for my profit.
