These started as wire wrapped trunks. The one with the terradon is a closer pic of the same tree set.
I then wrapped fabric that had been taken from a sport sock, soaked in glue/water mix and stained brown with some paint.
After this dried, I glued on some pieces of green construction paper that were cut out in leaf shapes.
Ta daa.
Jungle trees.
 

This one is just a twig that was gnarled. I glued some modeling lichen and a string (with crap glued to it) onto it and the rock. I will take this and some more wire trunk trees and attach them to a larger particle board.
