Hi Sam,
There used to be a shop local to me (Glasgow) that supplied faux plants, trees etc but they were extortianate! I just googled "artificial plants" and there were lots of links including one (on right of screen) for a company that supplies same for stage props - so they may well have what you're after ;) Again might be too pricey though ...
Is there any chance you could hollow out a real stump (assuming you can source the ideal size) to make it less weighty?
Just an idea - but maybe a c*#p one :rolleyes: since I can't picture in my head what you're trying to do!
Teri :P
