Hi Monika, I've only competed in a couple shows but from my experience I'd say the group having the show sets their own guidelines. May be different 'out in the world' but that's the case around here. Anyone have any other thoughts? Callynne
P.S. At a show I was at last summer there were beautiful leaves made from brown paper bags....you'd never have know it!! They cut two, put a wire in the middle, glued them together and then painted them. When the paint dried it curled the leaves up a bit and they looked awesome!! The lady said she considered them 'legal' because the paper bags were made from wood pulp....my kind of thinking!
