Required tool: Round Nose Pliers
Stick the tip of the pliers in the hole and give it a little push, slow and gentle until you make the hole big enough for your cord. This only works if you need a slightly bigger hole. I wouldn't suggest doing this to enlarge the hole more than a 1 or 2 mm bigger.
I'm thinking this is super cute for quick and simple pendants with my tiny charms. I'm making these to sell at the Farmers Market - if I can get a booth. It's a little tough getting in around here, but I'll try my luck in a few weeks.
Blog special: buy 4 tiny charms and get one free. When you check out include in the note section which charm you'd like as your bonus one! This special is good until Friday.
