This felt pom pom is handmade from a foam ball and good quality wool. This needle felting method is different from normal water felting balls. This 30mm felt ball is not pure wool, it is filled. Please kindly read the description clearly before you buy. Our filled felt ball is perfect for making fashion jewelry, home decor, or other handcrafts. The color is more bright and lasting because it is dry needle felting. And it is light not heavy, so you don't have to worry the heavy weight when piles up all the felt balls. But only one point, this ball is not good for making rugs, because it will be deformed if heavily crushed. Please feel free to contact with me if you have any question about our felt balls.
