Check out this mockup from Placeit! It's featuring a kid making an angry face while he's holding a yellow paper on his back, he's wearing a t-shirt while doing that too! The HEX tool to your right will let you choose his tshirt color, then upload your design and remove a black or white background from it using the menu on the left. Easy, right? Use Placeit and sell more tees! Try another T-Shirt Mockup!
