English to Russian Tech/Engineering Art, Arts & Crafts, Painting felting

Needle felting is a method of creating felted objects without using water. The special needles used to make 3D sculpture, jewelry, adornments and 2D art have notches along the shaft of the needle that catch fibers and tangle them with other fibers to produce felt. These notches are sometimes erroneously called "barbs", but barbs are protrusions (like barbed wire) and would be too difficult to thrust into the wool and nearly impossible to pull out. There are many sizes and types of notched needles for different uses while working. Needle felting is used in industrial processes as well as in individual crafting.
