Shirty something for t-shirts, decent blokes, good quality, short runs.
Plus it's the bassist from Sabbat.

Stickers are great quality and you can have them contour cut as well which would usually cost a fortune if you were getting them screen printed and cut. They are supplied on sheets though so you will have to do some cutting yourself, but a good craft knife and steel rule and you're golden. Kinda pricey, but cheap as chips compared to screen printed and you can do really short runs.
