I found this cute image on the Internet and decided to put them on some blank Tshirts I had dyed. I used the opaque iron-on transfers from Dharma Trading. I use iDye (also purchased through Dharma) on the stove to dye the shirts. I used blank white tshirts I ordered wholesale through American Apparel. I get a dozen of a style in white, comes out to about $3-$5 a shirt depending on the style.
