Needle felting is a crafting technique that involves using a special barbed needle to interlock wool fibers. By repeatedly poking the needle into the wool, the fibers tangle together, creating a solid shape. This method allows for the creation of various items, from simple shapes to intricate sculptures. The process is popular among crafters because it requires minimal materials—just wool and a needle. Needle felting can be used to make decorative pieces, toys, and even wearable items. It is accessible for beginners and offers endless creative possibilities for experienced artists.
