Nice online “clinic” on doing the supertrees there, Bill!
I have some techniques I use that takes the prepared supertree sprig from bare to ready to plant on the railroad in under 10 minutes.
Like Bill shows you need to do something to straighten and prep the sprigs to get the best looking trees. I select the sprigs I want to use (usually 50 at a time), dip them in diluted matte meduim, and hang them upside down to dry like Bill shows. If they need straightened, I’ll clip a closepin to the bottom of the sprig to straighten it.
The matte medium creates a rubbery coating on the delicate sprig and makes it a lot tougher. I leave the sprig hanging upside down to dry overnight.
Next day, like Bill shows, I stick the sprigs in blocks of styrofoam, then hit them with gray and/or light tan spray paint. I lightly accent the branches with black spray paint.
Here’s where I vary from Bill’s approach. Using this alternative approach, I get finished trees I can plant on the layout in a few minutes.
I spray the sprig branches with spray adhesive, then sprinkle on coarse ground foam. Don’t over do it here … one of the secrets to getting really great looking trees to to allow you to see through them somewhat. You can vary this to get some trees more dense, others less, but solid solid foliage you can’t see through on supertrees covers up the realistic and delicate branch structure, which is a waste.
Any green color of ground foam will work here because I next spray the tree’s foliage (just the foliage) with green spray paint to get the exact green shade I want for the layout. Tend toward yellow green shades for many species of tree, or a medium green for some trees like black oaks.
Then accent the foliage from above lightly with a pale yellow spray paint to simulate sunlight playing on the leaves … this last step will bring your tree to life, and is one of the “secrets” I use on the Siskiyou Line that makes the trees look s
