I think I posted my wip of these forever ago, couldn't find it with the search though. I made 2 plant containers with some hobby grass inside. I finally finished these the sad thing is I don't even have any figures that need cargo so guess I will just sit them on a random shelf ha. Made out of Gummi Lifesaver trays and various decals, the last time I got some Gummis though they had switched to a different tray design I think.
That's a great idea for a scene filler. I could see those working great with Joes, Star Wars or almost any kind of sci-fi diorama. Good work.
