Ok today i really got discouraged from my vinyl/t-shirt business plan. I have been saving to get me a vinyl cutter and a heat press so I can start to make t-shirts as well as vinyl stickers and things made with vinyl. Without giving away all my plans I was going to focus on sports related designs. After making my first design and sharing it with a "friend" they told me I couldn't use it because it resembled too much of a NFL team logo. I see people selling logo stickers, t-shirts with sports teams, t-shirts with movies/tv show themes, etc... What are the actual laws here? Is it something that just isn't enforced or what? Should I focus my money on a different business Idea?
