Finn helped me print some T-shirts last night, and they came out really well!
The ink is going on a little unevenly, so I need to work on my pressure and technique. I also think I need a finer mesh screen for greater detail; the one I bought premade is a little chunky for my taste. But I picked up some blue and white ink on sale as well as some more screen material at Utrecht, so I can start building and stretching some more screens for new designs.
