Thank you! The holder was a design my wife found that I kind of made my own, but in the future I would make the grooves a little deeper. I made them 1/4" next time I will probably go 1/2" deep.
Kelly Mountain Woodworks good call on adjusting the depth for the coasters. The thing I like about this the most is that it’s functional and decorative. They are also like mini cutting boards. Lol
