Brian, Thanks, it's great to be back in the basement.
Dave, thanks, working across the photo of the 4 trees, the heights are 13", 14"+, 12" and 11". I found a good price on 1/2 x 1/2 x 36 inch balsa square stock after the first two I got the tapering process down to about 10 minutes, scribe them with a razor saw, drill a 1/16 hole in the bottom and install some 1/16 inch steel rod with super glue for planting.
The branches are made from furnace filter material purchased at walmart, you have to tear it and tease it out or the tree gets to dense, then spray painted, then I used gorilla spray glue and short 2mm static grass on the branches. There's a couple more photos below so you don't have to go find my post from February about making these.
