Fabric Transfer Paper
Scan in artwork and print it out to the appropriate size for your t-shirt. Print the artwork on fabric transfer paper. Trim the artwork closely keeping the corners round for an easier transfer. Place the paper face down on your white t-shirt and iron following the instructions that come with the paper.
