OK. Let me answer some questions.
For leaves, I'm going to use Barley flack (sp?). They look just like miniature leaves. I'll glue them one by one to the tree and litter a few on the ground.
The tree is made from the root of a bush I had pulled out of my front yard when I was doing some landscaping this summer.
I've thought about adding a really small amount of snow, but am not sure what I want to use to create it as I want to avoid yellowing at any cost. I've had the most luck using marble dust, so that may be what I go with.
I made another trip to Michaels this weekend and they had some really small decorative wisk brooms that were perfect for the second type of grass I want to add. The color is the same as the taller grass, but it's a bit thinner and doesn't have the small barbs coming off the sides.
The figures I mentioned are the Soviet tank rider set. I agree that there are a lot of better resin figures out there, but to be honest, I don't feel like shelling out around $14 per figure.
