This one was commissioned by a friend for his parents. It is only my 3rd stopper and I am still trying to figure out designs that work out. So far, mine all seem to end up looking like this shape.
The "grip" effect is what I was going for. It is for a older couple from their son. Both have arthritis, so hand dexterity is a bit off. I thought this would help out a bit, and he gave me free reign to come up with my own design. His only request was the color and the ball marker inclusion.
