A piece of wire, or wire cut from a twist tie, is formed into a loop with a tail. The tails are attached to the interior of a pistachio shell with a layer of paper bits and glue.
Nail polish and/or black permanent marker is used to decorate the shell.
A photo can also be added inside. Attach with glue, then seal with clear nail polish.
A jump ring connects the two halves of the locket together. This can be made from a covered paper clip or piece of wire.
