For those who have been following this blog I give you something to ponder.
The first picture is of an upper layout level support made from a piece of 1/4" threaded rod. The branches are Woodland Scenics and are glued to the trunk with hot glue. I was going to use 'No More Gaps' a water based flexible crack filler but when I was gluing the branches on I just kept going. It worked fairly well. The tree is part painted with water based house paint from those little sample pots, very useful.
The final photo shows the finished support. The trunk has extra colours added using pastels and the foliage is light green Woodland Scenics foliage.
I will post some more when I move this little project along a bit further.
What I can say is that it will add a another level of operation to the layout, sorry for the pun.
