These are plastic trees(Jarvis I think? They've been out of their bags a long time!) They're either based singly on some warbase circular bases or two to a base on redundant CDs (as suggested by Stew on his blog: A terrible loss of lead and wealth) then based as normal,I stuffed some foamboard under a few of the shorter trees, that seems to have worked out. Rather rapidly painted in the end as it had all taken so long!
Next, more trees, winter ones this time! Churches,I'm working on cypress trees that aren't made of pipe cleaners! Oh and maybe some figures?
All the best Iain
