DIY GRAPHIC WORD TEE. You Need: •T-shirt •Iron on letter •Scissors •An iron •A piece of cotton. Cut letters out. Lay the letters down plastic side up on the t-shirt and play around with your placement. Put the tee with letters in place on the ironing board and cover with the cotton. Iron the word on a low heat setting. Once you have done that for a few minutes, turn the tee inside out and iron the other side of the letters too so the glue sets really well. Remove letters.
