i don't know if i made up this technique or not. i can't find it anywhere but i'm also not an expert stenciller by any means. i used an index card, clear packing tape, and a craft punch to make a teeny tiny stencil. then i used it over and over and over to make different designs.
this is my favourite one by far. the whole design is done on the back-- it's supposed to look like a gunshot wound from far away but then when you look closer it's all made of different colour hearts.

here are a few of the other layouts i tried. all of them wrap around from the front to the back of the shirts

i'm totally in love with all my new shirts. i can't wait to go back to the dollar store and get a bunch of new hole punches.
comments/criticism appreciated!
