All but one, technically–the first prototype that I carried around for a while–but it would have made the mosaic uneven. (Yes, it could have been 7×3 to accommodate 21. Didn’t like that shape.) Some of these are still for sale in the Etsy shop; some are sold, or donated, or swapped; some never appeared in the Etsy shop, because they were custom orders, or because I’m using them myself.
Stay tuned, more to come!
