This 20mm foam filled dry needle wool felt ball is perfect for making garland, fashion jewelry, or other home decor craft projects. It’s not heavy, so you don’t have to afraid piles of the balls will damage the shape of your craft. There is no hole on the ball, but you can simply pierce it by using a normal needle. About color, I try my best to show the most correct color but it may vary a little due to the light when taking photos, or due to different displays. Please kindly contact with us if you have any question. I will be attentive for sure.
