Bead Exchange bracelet.
I invited friends on my journal to send me a bead that they thought represented me, and I would send each of them a bead. (the charms were also gifts) Once I collected all the different beads, (from all over the world!) it was simple to purchase some clear beading elastic and thread on the beads to make a bracelet, you simply tie off the ends with a few knots, adding a few drops of clear nail polish to keep the ends from fraying.
I suspect you could also thread beads onto a cord to make a keychain, or if you had enough, make a necklace. But now it’s fun to wear the bracelet and think of the friends who sent me each one, and the good wishes that came along.
I sent each friend a coloured bead, but also the large faceted black onyx bead for protection.
