That's the what I think when I finish filling a ware board with sponge holders. They are easy to throw and make good kiln fillers. They can be placed around bowls and vessel sinks, as well as sit on the bag wall during the firing. I call it throwing money because every single one of them sells in no time at all. I am trying to get in the habit of throwing at least one board full a week. That way I won't get bored throwing a whole bunch at a time... because yes, they do get boring.
Last year I nudged the price up from $15 to $20. When I was pricing them at $15 and they were selling like crazy, I felt like I was doing a lot of work for very little money. At $20, they are worth the effort.
The nuka white glaze with the carved design has been the biggest seller for the past six months, with aqua shino running a close second. These little items are certainly no amazing works of art, but people love them and they help pay the bills. I have finally gotten over the shame of being a sponge holder maker :-)
