I made these for a PETA2 "DIY Chick" event. They are very simple and easy to make. Just be sure to use water proof and sturdy pictures.
Cut out pictures and glue ones for the bottom on to the clip/latch end of the safety pin.
Put glue on center of top picture and stick the other end of pin it.
Stick stud in the center of loop in pin while glue is still hot.
Let cool and enjoy!
