I used the pattern found here. I just modified to insert folded ribbon in between each section of material. I used the biggest size and they are pretty small...perfect for younger babies so they can hold them easily. I love the girl version because the fleece material really helped to give it a nice round shape when I stuffed it. The boy version was a little lumpy, but still cute.
The best part was as I was stuffing the balls, John immediately came over and wanted to play with the balls before I could finish sewing up the opening. He LOVED them! So these are kid tested and kid approved! :)
