Individual Groz-Beckert barbed needles for reverse needle felting. Needle felting is a technique used to turn fluffy, loose fibre into felt. Repeated passing of a felting needle through loose fibers tangles and compacts the fibres, shrinking the mass gradually until the fibres remain packed together – which is felt. The reverse needle allows you to pulls tufts of fibre out of your felted piece. This is great for adding textured effects to or pulling inner colours out of your felted pieces. The reverse needle is also an invaluable tool for wet felting, allowing you to pull fibre to adhere new additions to.
