An Armful of Stretchy Bracelets

I found this in my jewelry box:

and it was so lonely, I had to make more:

I strung the beads on stretchy elastic and tied a double surgeon's knot.  The ones with silver charms also got a crimp bead to squish the cord down, and for good measure I dabbed on a bit of glue to the knots (I'm always afraid the knots in these kinds of bracelets will untie, although they never have).
