There are many processes to create felt but needle felting requires only a needle and fiber. The needle pierces the fibers, agitating and entangling the fibers, known as felting. The size of the needle depends on the project and the aesthetics. 36S, 38S, and 40S should be used for finer felting. 36T and 38T is perfect for coarse and medium felting. For larger holes use 36, medium holes use 38, and size 40 for finer holes.
Sizes: 36S, 36T, 38S, 38T, 40S
