I also made some reusable price tags. This is not my original idea, I saw another potter using these, and I don't remember who it was. I rolled out long coils of clay, then cut them into 1.5 inch nuggets, with one end cut at an angle. I glazed them with my glossy liner glaze, and now I can write on them with a dry-erase pen. Unlike the paper tent cards I used before, I don't need to tape these down when outdoors. And now I can easily change prices in the middle of a show.
