Thanks for the kind words everyone.
The first thing like this I ever did were the toy display backdrops.
Each one of these full-page PDFs can tile horizontally, so print out as many as you need and line them up side by side. I designed these for playmobil set-ups I had, but they're generic enough to work with most action figures.
I also designed this scale model Vegas style Craps table. A little big for Minimates, but good for Star Wars, Playmobil and other 3 3/4 sized figs
