I don't quite deserve the compliment, but thanks! Those are SOS pads on the dowels. If you can find the heavy duty industrial kind they will support themselves better and won't sag like the ones I have on those trees. This is what I learned in the class:
Get a dowel or any stick that you would like to use, then take either a saw blade, or a wire wheel and mark the stick up to simulate the bark. You can then paint it, stain it, or leave it as is. Then take the SOS pads and rip it apart, actually you gently separate it so that it is in a thin layer, then stab the stick or dowel through the pad. Once you have enough pads on the tree for your liking, then put ground foam on it with hairspray. Don't be shy with the hairspray, you may need to coat it on pretty good. After the tree dries, you can go back and cut the hanging frizzley stuff off. The instructor had great looking trees, but I haven't had too much luck in getting my trees to look the same as his.
As for the sagebrush and rabbit brush trees. You'll need some more ground foam and some of the poly fiber stuff. The instructor suggested that you use a variation of lighter colors of ground foam for these trees. Take the poly fiber and gently pull it apart and form a very light thin layer, so light that you can barely see it. When you think that it has been spread out enough, then spread it a couple more times. Then take your sagebrush and wrap small amounts of the poly fiber in the inner branches. Then spray it with hairspray and lightly sprinkle on some ground foam. Don't go over board because you want to keep the airy leafy feel to the tree. Add another coat of hairspray and when it is dry spread some more poly fiber around the outside branches and apply ground foam like before. The key is to wrap the poly fiber around the branches so that it takes shape to the branch, you don't want it to look like blanket that covers the top of the trees. By doing the inner branches as well as the outer branches it is supposed to give it more depth.

I hope this has made sense. If you have any questions or want pictures feel free to ask.
