In a nutshell, it's the process of transforming wool into 3D objects using a barbed needle.
When you felt wool, you're agitating the fibers so they bond together, creating a solid fabric. If you've ever felted any of your knitting projects, you're already familiar with the process — except that you probably used a washing machine with really hot water to get the fibers to bond. Needle felting mimics that process, but instead of agitating the wool with hot water, you're doing it with an extra-sharp needle.
The Twisted Ewe offers a small selection of Needle Felting supplies and kits for everyone to try their hand at it!
