Once you start designing and creating, there are a few tools and supplies you'll want to keep stocked up and in good working order. You'll be using a lot of head-pins, and eye-pins while your cutting tool, or "nipper" will take a lot of abuse. You'll want to replace the tools every couple of months for a fresh sharp blade. Usually at that point, we will start using our old nipper to cut thicker chain to get some additional use out of them. You'll probably always want a bag of each type of head-pin on hand, along with crimps, crimp covers and earring findings.
