When I was wandering around thrift stores looking for ties, I also had an eye out for mugs that would work for this project. I found three (that's the way, isn't it?) IKEA mugs for a buck each. It was a price I was willing to pay.
Then I bought an oil-based Sharpie because I couldn't find the pen that Crafts by Amanda had used in any of the nearby craft stores. (I've got all three at varying distances.)
Then I waited until I was nearly broken by my National Craft Month craft-a-day challenge. And I drew mustaches.
