Here is our method for modeling trees with Clump-Foliage, which provides a very thick, realistic looking tree.
1. Bend and twist Tree Armatures into realistic, three-dimensional shapes. A popular technique is to have the branches resemble deer antlers. This shape helps hold more foliage on Armatures.
2. Apply Hob-e-Tac (S195) liberally to all sides of branches, avoiding trunk area where foliage does not grow naturally. Wait for adhesive to become clear and tacky (very important). Dry time varies due to environmental conditions, 20-45+ minutes.
3. Break Clump-Foliage into manageable size pieces that are proprotional to the size of the Tree Armatures you are using. Dip the Tree Armature deep into the bag of Clump-Foliage, remove carefully and shake gently to remove excess. Dip into bag of foliage again, if desired. Then, pinch Clump-Foliage firmly on branches to secure.
4. Overspray Clump-Foliage with Scenic Cement (S192) to help seal in place.
