Ok so i'm just a 13 year old and a few days ago i got an idea for a deck of cards, and so later that day i got out photoshop and made the back and all the fronts for the whole deck but now what i have a tuck case design as well. so i went online and ordered it to print so i could have it and show my friends but i'm pretty sure it'll come out with the image of all the cards cut off. the thing is i don't know how to copyright the deck or even how to print it that well, or if i should sell it to someone or sell it on my own, keep it to myself or if anyone would want to buy it. I am clueless and i am confused and worried and panicing thinking someone might steal my design. If any of you want to see the design for better advise for me then tell me.
