Step 11: Pictures
Printing them was for me difficult. I had a lot of difficulties getting them out in the right size (18mm diameter), and ended up just printing one, measure it, adjust, print, adjust, print and so on. The final images are printed on photo paper, to get the best quality possible.
When printed, cut them out and glue them on the pin. I used superglue again here. Make sure you angle them right, so they aren't off when you view then in the finished locket.
