They are certainly interesting and attractive enough for selling.

It might be a good idea to find a shop where the owner is interested and will be enthusiastic. Keep in mind tht the cost of making them has little to do with value. If you can be promoted as being an artist...you can charge enough to reward the shop owner well enough for her/him (or whatever else) ...to be enthusiastic.

Another avenue to explore. Keep in mind that small newspapers are always looking for articles to fill up their pages. Don't ask, offer to be interviewed, if they are positive and can include a photo of what you create...
