OMG, these are AMAZING! Next time I am bit by the crafting bug, this is one to try. My fav are those in #3 - but the work to get the little bound book is INTENSE! (Roundup of DIY Mini Book Jewelry Tutorials)

Incredibly detailed pin on how to make those tiny books that fold open flat. I have tried to do this before, but never had clear instructions, this may work way better! Off to try again when this quarter is out!
