Glass coasters are actually really awful to use for tall, sweaty, muscular... uh, glasses. But they display nicely, and I s'pose if you really loved them you could buy a mini easel and rotate them out as a desk display. (Or dashboard art, if you drive politely.) I got them because I wanted a few things to display at my workshops so people can see how they can put their newfound talent to good use when crafty/Christmas season hits. Lots of people I know are really into homemade gifts these days... and Pinterest is exploding with great ideas. Ornaments... gift tags... greeting cards... earrings. *shiver*
So happy to be on this bandwagon.
