Oh, alright then!
here's the slightly mad plan, another thing I've not tried before, and the explanation behind the skirt flaring up too.
Step 1: a Diet Coke can, sacrificed:
Step 2: covered in a layer of Fimo and baked. I kept a texture in it because it will probably be a long military coat type affair:
Step 3: held against the model to check fitting. Not bad; a bit of trimming and it will sit on nicely, I think. As long as the glue holds...
The aim is to have a coat flowing in the breeze. Does it work, everyone?
