I designed a decal which themed from a popular home game ie beer pong. I came up with this on my own, I am really new at the legal sides, but I would like to know how to make this my own, in other words I will share it but I also would like to sell it digitally. does anyone have any ideas on how I might go about doing this? my nieces friend slapped it on his laptop all his friends saw it and now they all want one. any advise would be very helpful Thank you in advance.
