Here's something we did a few weeks ago, and it was too cute not to share. Twig dolls! The photo kind of explains how to make them -- just find appropriately shaped twigs, tie them together with pipe cleaners, and add accessories depending on what you find outdoors. we made these fairly early in the spring, but I can imagine wildflower skirts, acorn hats, dandilion heads, etc.
A great nature/creativity craft!
