Tiny snowman in a tiny snow globe

What is small enough to fit into a half-inch tall glass bottle? I could only think of model making figurines, but the ones I found didn’t have the squee factor…
As I love re-purposing and experimenting with different materials, I thought I might as well make my own little winter scene. Here’s the result! A tiny snowman (complete with carrot nose and charcoal eyes and buttons, yessir!) next to a tiny fir tree. And if I shake it, it snows:

less than an inch tall

Can you guess what the fir tree is made of? You can win an original ACEO drawn by me ;) – I’ll announce the winner (chosen randomly from all submissions) and tell you the right answer next week.
