I can't resist boxes - wooden, ceramic, metal, etc, as long as these are sturdy enough to hold a miniature scene. Sizes are not a problem when you make your own miniatures, you just have to worry about proportions.
Here is photo of a garden scene I fitted into a ceramic box. I made everything inside, the terracotta planters, the ladder and wheelbarro and used popsicle sticks for wood. The plants are bits of plastic artificial flowers and leaves. Wish I'd taken photos of all the diffenrent sized boxes scenes before I gave them away. I do not sell but enjoy giving present to people I love.
