wonders why create different 3D models, if you can create one that can be customized?
I'm always on the lookout for inexpensive terrain, and so when I saw this package of "floral decorations," I thought - it's $1 USD per pack, why not throw some on the tabletop and see what it looks like?
My best guess is that these are supposed to be moss-covered rocks. Upon opening the package, I found there were five of these rounded objects, very lightweight and covered with grassy material.
My first worry was that - since they didn't have a flat side - they might roll around too much on the tabletop. So I grabbed a hill piece, tossed some rocks on it, lined up some troops, and took a picture. (Yes, the rocks do stay in place.)
At $0.20 USD apiece, they're dirt cheap to scatter around your tabletop. They do a good job of breaking up line of sight and giving your troops something to maneuver around. But I wouldn't try standing a figure on top! As for appearance... well, it's up to you whether you want to bring them home to Earth, or leave them on some fantasy world or distant planet.
