The supplies needed are a plastic milk or juice carton seal, 24 gauge wire, jewelry cord that looks like thin rope, tacky glue, scissors, needlenose pliers, and I found a set of small hemostats to be helpful for pulling the cord.
Start by cutting the ring off of the seal. Don’t throw away the other part as it makes a great plate. Then cut 7 or 9 four inch pieces of wire. Be sure to use an odd number. Bend over about a quarter of an inch, hook that over the ring and crimp down with the pliers. Once it is crimped into place, use the pliers to twist the end of wire around the longer tail. Space the wires evenly around the ring.
Cut an 18 inch or so piece of cord. Wind it round and round the plastic ring until the ring is covered, being careful to keep the wires spaced evenly. When you reach the end of the ring place a tiny amount of tacky glue on the last bit of exposed plastic and glue the cord in place. DO NOT cut the cord.
