A while ago I posted some photos of some new round button coasters that I'd just made. I've now glazed them and listed them in my shops. These are denim blue and the next batch due out of the kiln will be green. There are also a few other patterns and new colours too which will be launched for Christmas.
They will withstand the heat from your hot winter drinks, they have four rubber feet on the underside to stop them slipping or marking surfaces.
