I made these hearts about a week ago, but only just got around to cleaning and photographing them.
They are the kind that is made on the very end of the mandrel, so the hole doesn't go all the way through. To prepare them for use, you make a double loop of wire with long tails and then epoxy it into the top hole. Then you can either hang a bail onto the loop or thread the chain/cord through the loop - depending on which direction you glued the loop in. Clear as mud, right?
These beads can be found in my Etsy shop.
