Whenever cutting wire, eye protection is a good idea. Memory wire is tough and requires heavy-duty cutters. Lighter cutters will dent, or even shatter when cutting memory wire!
For a finished bracelet the size of 1 coil (6"), use heavy-duty cutters to cut a piece of wire approximately 1" longer than a full coil. (For a 7" bracelet, cut a piece of wire approximately 2" longer than a full coil.)
Cut a second piece exactly the same size as the first.
Use sturdy round-nose pliers to bend a tightly-closed loop at one end of each wire.
When stringing the dagger beads, alternate the tips: left, right, left, right. String the dagger beads onto both wires at once.
When adding seed beads, string the same quantity of seed beads onto both wires each time.
For this design, start with a dagger, add 10 seed beads to each wire, add a dagger, then 9 seed beads, a dagger, etc.
Finish with as many dagger beads as necessary for desired length.
For a 7" bracelet, start with a dagger, then 11 seed beads, then follow the pattern above.
When done, trim any excess/uneven wire, and bend a final loop at the ends. Be careful so you don't shatter any beads!
Check for rough edges, and trim or re-shape as necessary.
