For my TMNT Sewer, which I will post soon, I've been making some accessories. I've always like the idea that the Turtles and their father made their home in the sewer with furniture and appliances they found. Discarded items that maybe broken, but still good enough to use.
My sewer set will also have a TV/living room and that wouldn't be complete without the iconic, 3-seat sofa from the original cartoon. I also made the wooden coffee table based on the 80's cartoon. For the sidetable I sculpted half an oil drum. Sculpted from epoxy and painted with model paints.
