If you have any solid wooden poles please reply.  Tapping sticks are quite expensive to buy so re-using wood or thick pvc pipe would be great.  The sticks need to be between 20 and 25 cm long and between 2 1/2 and 4 cm thick, with smoothed-off ends.

and more resources: I can make this caterpillar, so if you have an old air mattress please bring it in.
