Bear with us - the Lumi process is kind of involved, but if you can do it, it's a cheaper alternative to silk-screening. First, buy the Lumi Inkodye Starter Kit ($30) with the help of an awesome intermediary website - we suggest Outblush. Then, once you have it, roll the Inkodye onto your shirt or other fabric item - cotton, linen, silk, rayon, and canvas all work, as will other absorbent fibers. Pin the negative of the design on top (you can create a negative with the Lumi app and have it printed and shipped to you) and leave it out in the sun for ten or twenty minutes while the UV rays develop the picture. Next, remove the negative and throw the cloth in the washer to get rid of the undeveloped Inkodye. Finally, enjoy the art you (pretty much) made yourself!
