Firstly, Thank you for your time on the forum and helping trying to sort the confusion out.
But another question. Lets say I make a pattern for a plague. Somebody wants to use it, and I am happy to share for free, but if I understand correctly, because I designed the pattern it is automatically licensed to me. So weather I sell it or give for free, I have to have someway for my customer to get a license to use my pattern.
