Made this with a knitting loom. Using two pegs, you knit it as an I-cord. First, you string the beads, make a slip knot on the first peg, and e-wrap the next one. Continue to e-wrap the two pegs, knitting off each time you have two wraps on a peg. Gently tug on your work as go and stop at 7 inches. Knot your ends together and weave in the tails.
