Wild Woolies are eco-friendly, fair trade felt designs. Yes! It can be hung outside as well as inside, and yes, small birds like wren, chickadees, nuthatch and titmouse will go inside! Made of 100% naturally water repellant wool, so when it does get wet on the surface it dries out fairly quickly. Wool is also naturally dirt and mold resistant. Birds might pull at the wool to use in making their own nests. Hang one up and see what happens!
