I cut up the top layer of the squares pack to the shape I wanted - you don't have to use them as is. And then, I went to town on all the details!
Here's a birds-eye view:
The large cotton reel supports were rusted up,
as was the stencilling onto acetate on the sides (supposed to look like old pier struts):
I used Oxides to colour the fish and that's a bit of orange netting in the background!
Thanks for looking!
