Sometimes folks will request things that I don't think about doing. I've had a request for buttons for some handmade hats and shawls, etc. Since texture is one of my trademarks, I have been having fun with little pieces of clay. These found their way into the kiln around all my larger pieces.
I like the fact that all the areas of kiln shelf were covered, thus making it a very efficient firing. I call things like the buttons "fillers" and have been doing that for a long time. Sometimes they are paperweights, sometimes medallions, and now buttons.
