I'm looking to make a couple simple pairs of earrings for my young niece, but am having trouble finding the right kind of backs. She's still little, and the only way she'll leave her earrings alone is if they have the closed backs that they put on piercing studs. My Google and Etsy hunting skills are failing me, and I haven't seen them at the regular craft stores around here (Michaels and AC Moore). Does anyone know where I can get these? Or even if they're sold separately without having to buy the actual earrings?
