I added 10+ yds of twine and 2 full skeins of embroidery thread. these were cut into branches of varying sizes. Some were separated into single ply. This is the jumble of branch work under the trees.
Three different fabrics, shades of orange were added. I can't say these were applied in a totally random manner. They were sprinkled, but clumped to give the impression of individual trees or branches.
The photo order reflects each side, the first with the thread/branch work and then the overlay of "leaves".
First the left side..
