I have used them for my 88mm gun emplacement diarama. They do have some nice stuff but again this stuff is not cheap.
I really can't figure out why it costs 24.00$ for a single 20 inch tree. really seems way over priced i think.
Tankhobby has the best idea about using the
christmas table top trees when they are around. you just need to pick up a bunch of them when the season comes around. they are very inexspensive after the holidays.
