Wild Woolies Collection Collectible Birdhouse Bubbly Submarine Sub Item #: 484076 Material: 100% Felt Sheep Wool Color: Yellow Fair Trade Certified Sheep’s wool is an amazingly adaptable fiber. It can be dyed any color and when hand felted it can be molded into any shape or cut and sewn together. Wool is a natural and sustainable resource that continues to grow each year after the annual harvesting of the fleece. The felting and most of the stitching process is all done by hand resulting in products with a relatively soft impact on the environment.
