Between keeping up with daycare, nurture my own children, teaching yoga and my other endeavors I have managed to felt about 10 balls. Not the 15 I wanted but hey nobody's perfect.
After needle felting them I always wet felt them to give them that extra strength. Kids love playing in water so I figured why not do it as a group activity. They loved it!!! They loved squeezing the water out and so did the balls with every squeeze the fibers got stronger :)
They still need to go in the washing machine for yet some more strengthening :) So stay tuned for the end result :)
