Hi.
Andrew is right, although the banana leaf shape is slightly different.
The key difference is the trunk, which is made by wrapping the wires with strips of masking tape which have been cut down the middle using pinking shears, Pinking shears are scissors designed to cut a zig-zag line raher than a straight line. Starting at the top of the trunk, wrap the strips to spiral down the trunk, keeping the zig-zag edge upwards. Paint it in a darker shade of the required trunk colour and dry-brush with a lighter shade to bring out the texture.
I'll provide more detail with some pics soon - although it's virtually 20 years since I actually made any!
One of our fellow adventurers has kindly offered to put my stuff on his site, so I'll do that and provide links from here.
