How about just taking a small piece of line and tie it into a loop passing thru the hole where the bead used to be. Just tie it with something like a zeppelin bend or some fairly large knot and the knot will become the bead. Or if there is nothing at the end of the whoopie to tie to just tie it in a knot, like and ashley stopper knot and that should be large enough to keep from getting pulled in.

Deep peace of the flowing air to you.
Deep peace of the quiet earth to you.
Deep peace of the shining stars to you.
Deep peace without end to you.
