Anyway, after regular stints selling stuff on eBay and our own domains we eventually used Etsy as the primary place for selling these pieces online. Most everything about Etsy was cool and from the beginning the response we got from the Etsy shops was seriously humbling. It was as close to an instant success as we defined it. [What we posted typically sold and always to some very nice reviews.] There was almost more business than could be comfortably handled and slowly I stopped posting new pieces there at all. The goal wasn't to make money or sell a lot of pieces. A small selection at a simple price to simply make the art available online. But it became a lot of work.
So for the last couple of years the only time you could purchase any of the pieces from the project was if you went to a gallery show or an art festival or something like that where they were being shown. Some locals brick and mortar stores were cool enough to carry a stock of them too but that was all.
For a while now I've been trying to figure out another way to still be able to easily offer at least a small but steady supply of new work for sale online. It sucks to not be able to interact that way when people inquire about how to buy some of the pieces for themselves.
So the Etsy shop has been reopened.
