I'm totally going craft happy over bottle cap necklaces! I made this one the other night:
And then we had a girl's night where we all made necklaces!
Tips for making these is: pour the epoxy on while the bottle caps are on plastic cups (like those big red ones people use at picnics). That way, after the epoxy is cured the epoxy and cap will pop right off the plastic. Also, use cute bottle caps! Izze pop has the cutest ones (I think :) and it's yummy to drink too!
