Making rings doesn't have to be hard, expensive, or require a lot of fancy tools. This instructable shows you a fast and simple way to make stackable rings.
Step 1: BoM
Glue (super glue, jewelry glue/epoxy etc.)
Step 2: The Wire
You can make multiple rings in one shot by wrapping wire around a ring mandrel several times. It's okay if the wire is a little loose on your fingers, you'll be cutting the spiral in several places to make multiple rings.
I generally opt for a thicker gauge or half-hard wire as long as it'll accommodate the beads I want to use. It'll also help keep the rings' shape. Memory wire will also work.
Step 3: Snipping
After you have your spirals shaped, remove the wire from the mandrel and begin snipping. You want to snip at the same or just a little less than were the end of the wire meets to form a full circle.
Depending on the size of the beads you use, you may need to snip a little more off the ends to fit both wires inside.
Step 4: The Beads
Selecting beads that fit the wire gauge you're using, slide the bead onto one end about 1/2 through and add a dab of glue. Slide the other end of the wire into the bead, add more glue if necessary. Set aside and let dry.
Step 5: Repeat
Repeat the previous step as many times as you want.
