Small pieces of wire. .028 goes in a plastic bowl, about 3 " across. I use it for rests, sometimes springs. I use mostly .020 for springs in acrylic.
.036 goes in anothe small holder, used for RPEs, etc.
.030 goes in another holder, I use these short pieces for making lower lingual arches provided they are long enough. Shortest ones I use for 2X2 arches.
I accumulate these pieces as I go during the day. Rather than toss out the bits, they find a home elsewhere.
Thing that is a must....keep the sizes separate.
Use goodies you can find at the stationary store. I found a goody years ago, still in use, that has 3 slots and 3 drawers. Tiny slots and drawers, about 1" wide by 3" deep. One of the slots hold .036 wire, drawers hold expansion screws for Schwarz, Sagittals.
RPE screws are stored in a small box in a cabinet right next to me, easy reach. I keep the T-Rex screws there as well as Herbst parts etc.
In a pinch Cade, if you run out of TP, shower curtains make a nice substitute!
