Pumpkins are some of my favorite miniatures to sculpt. The steps to make these delightful orange squashes are pretty simple and outlined here.

Sculpting a White Oak Acorn
A recent art project of mine was a white oak acorn sculpture. White oak trees are prolific throughout eastern and central North America. In autumn, their ovoid acorns change their hues from green to brown and fall from their branches. They collect on the ground and are inspected by squirrels, chipmunks, blue jays, and me.
