Next I freehand drew a circle onto two adjacent sides of the square. I cut out both circles and ended up with a crude sphere.

I took the misshapen sphere to the person I was making it for to see how well it fit in their hand. I checked to see if it was still too large or too small. It was a good fit, I took note of how and where their fingers grasped it. The person has two contracted fingers with very limited movement and the ball pushed outwards on them.
