I've made a coaster like this once before, and I will say, they do hold up (like a Buckeye!). I've had it on my desk for a year and a half at work, with sweaty water bottles and my beloved Diet Coke.
You can read all about this Buckeye coaster over on the A Jillian Vance Design Blog.
Thanks so much for visiting my blog today! Make it a great week!
Go Buckeyes! Beat scUM!
