needle nose pliers, chain, individual round links, charms and if you want, you can use beads to add a little flair. i make mine long enough to slip over my neck, if you want them shorter, you'll also need clasps. because the chain is cheap they break easily... luckily, the chain is cheap. it's also easy to fix. i get everything at hobby lobby and michael's. they have different selections of charms... so i always explore both!!
