Sorry, my hair gets fucking everywhere. But all i did was cut holes in the shirt, realise i didn't like it, and sewed them back together. The only thing you need to think about is the colour of the thread, black with white- simple, and which way you want the ends of the cirlce to stick. That is, either in or out, as a circle sewn together is a semi-circle. I was unsure, so i did a bit of both. I also think its nice to have it quite messy, this also means it's quick!!
