For the trees, I collected together various sized twigs I found outside, although
I still made sure that most of the twigs were somewhat taller than the modern
sculpt joe figures. To make one tree, I took some green plasticine and rolled it
into a ball. Picking up one twig (making sure to clean the twigs before use) I
pushed one end into the plasticine ball. I sculpted part of the plasticine up the
end of the twig, then pressed out the other end of the plasticine into a flat
disc. This made the plasticine into a tree base, and it was then possible to stand
the twig upright.
