I am making my own set of racks and tubes or test tube division
with pony beads (from Wal Mart) and these sets of printable boards
from JMJ Publishing, game pawns, disposable plastic cups (cut down to
dish size containers for the beads) or any tiny bowl or container will work.
Craft bead tubes can be used to store each set of 10 beads.
The "boards" can be printed out, and then mounted on a heavier board
with holes punched in for the beads, with another board for backing glued
on to the board with the holes. All of this can be stored in a boxes or trays.
