I’ve covered making trees here before but I’m always on the look out for new techniques.
I recently came across this approach and have been impressed by initial results.
It’s from a scratch build modelling buddy on Instagram — find him at Instagram/timecapsulescratchbuilder — and although his technique is simple it creates tremendous looking model trees.
In a nutshell, the trunk and branches are made from twisted florist wire (see photo below). This is then covered in Milliput (an epoxy putty) before painting.
Finally, foliage is added with multiple layers of flock from Woodland Scenics glued with PVA or similar.
As you can see it creates wonderful trees and by using flock rather than sponge, suggested in a previous tip, the finished look is far more realistic.
Alternatively, If you don’t have the time to make your own trees or are artistically challenged you can get ready made trees here. The quality and variety is better than ever before.
