These 100% natural wool needle felting mats are my absolute favorite surface to work on! This mat is made of solid wool which has been wet felted to give it great durability and the perfect amount of support when using it as a work surface for needle felted sculptures and wool paintings. It is solid enough to support your work without it sinking into the pad, but has just the right amount of giving to take repeated pokes of your felting needle without sacrificing the working surface of the block or causing needle breakage. This 100% wool felting mat measures 9.5" x 9.5" x 1.5", and is great for larger needle felting projects.
