Oh how nice! I personally think it is perfect like it is. But, you could add a border to the outside if you wished to give it a little something.
My tool came up missing after a visit from someone who must have wanted one. I bought a new one recently and plan on trying to get one made. I also got a spicy spiral pattern in the mail yesterday, so that is in my near future too.
I love how these smart women have made these tools for us to enjoy. It is really so cool to make something the easier way.
