Plus it's easy to do so! Make yourself a redbubble account, bound it with your paypal account (If you have one), post your arts that you'd consider potent for prints, publish them there for sale and voila! Just sit and wait for eventual results and add some more in the meantime.



And I wouldn't be surprise that your future prints may sell, I mean, I'd buy this art right here if it was avalaible as a print.
