12. The dried plaster contrasts with the second darker layer,
allowing you to see where coverage is needed.

another coat or two of fresh plaster. The new plaster will seep in

burlap permanently in place.
Planting trees
Any model railroad running through the Oregon Cascades
needs at least five important scenic features: trees, trees, trees,
trees – and what was that last feature?... Oh yeah! More trees!
Burlap-based scenery support shell ends up being fairly thin, and
initially we were worried about planting trees solidly enough to
resist ordinary abuse. There can be a fair amount of torque on the
scenery at the base of a 12” tree when that tree gets bumped.
In order to distribute the stress, 1½” blocks of bead board insu-
lation material are hot-glued smooth side up under the scenery
14. Glue support wires to tree trunks to allow them to be
poked through the hardshell to plant the trees.
