I am in the process of making some new tree stands, so I went looking for some advice. I like the way these turned out.
Dramatic Katastases has a nice, if brief, post on making stands of trees. I think I’m going to convert a few of the trees I have on washers over to this setup. They will be more stable and add a little something to the table.
Here are some instructions from an old model railroad magazine on making model trees.
The Corbania Prime Blog has a nice illustrated tutorial on making heavy — jungle — foliage terrain pieces.
