Thanks everyone!
The hedge is made of two layers of 1/8" hardboard (the kind with the textured back), with the top layer being smaller than the first to define the raised portion. Then spackle then textured with sand and rocks. The main thing I wanted to work out was the foliage. It's polyfiber (the kind for pillow batting) glued and the spray painted. Then I brushed on a 50/50 white glue and water mix and applied course turf from woodland scenics. The spray paint makes the polyfiber harden to be real durable and the courser flock I think gives a more natural look. I wanted to try painting on the glue instead of spraying it so the interior would not have flock stuck to it.
The tree was the first test I made using a 1/8 inch dowel in polyfiber batting glued, spray painted and flocked on the end. I already thickend the trunk once with fine ballast but think it needs more. I thought about using a thicker dowel but want to keep the hole on the base as small as possible. I also thought about winding a wire around it but am trying to get it to where I can make a large number of trees without a lot of work(this one prolly took 5 minutes). Might just use a courser balast on a first thickening pass then the finer on the second to bulk it out more.
