Hobbyists licenses to hand produce USMC items [that fall within their guidelines] are $25 yearly.
I tend to agree with this policy, which aims to stop the production of USMC panties, socks ect.

From what I gather, if you make USMC items for non commercial/retail purposes, that is not regulated.
So technically, you could make something then keep it, or give it away ,,, But if you make a single $ on it, you must be licensed.
