These are the product of a lot of patience and a lot of trial and error, for me, though, I link this back to my childhood. I've always made things out of stuff you'd otherwise put in the bin. My currency was toilet roll tubes and cereal boxes. I would make fortresses for my action figures out all sorts of things. Cleaned out tin cans with both ends opened made perfect sewer pipes for Teenage Mutant Ninja turtle action figures.
