To make this activity, I cut small pieces of sticky backed velcro (the sticky side) and put them all over the ball. When I was making it, O was wearing a fuzzy hat that I knitted for her on a round loom. I threw the ball at her head and it stuck...the look on her face was priceless! After that I thought we probably shouldn't use the hand knit hats because the threads pull out with the velcro. I thought the knit hats from the dollar section of Target would work well, but they really didn't. I think the knit is just too flat. However, we had a great time trying to get the ball to stick to O's head. The novelty of having a ball thrown at your head and actually doing the throwing was very entertaining for both of them.
The gloves (from the dollar section of Target) worked well for catching the ball.
O's tutu worked best of all!
I saw this activity somewhere last winter...probably either in Family Fun magazine or on a blog.
