I like to be frugal, whether I'm shopping for groceries, pet supplies or hobby goodies. This is why unit fillers in WFB appeals to me. My two Saurus units presently have 20 models each, but I want to expand the units up to 24. Inexpensive solution, take the 8 unpainted models I have and turn them into unit fillers. After sketching out some crude diagrams on post-it notes, I've assembled the first one.
