It's not a gallery, but my local public library does month long displays of local artist's works. Newspaper interview and all. I can put price tags on them too! They have agreed to show some of my work in May 2010. Depending on the size of the pieces, I could display 25-30 pieces. I have about half that many. So... now I have an excuse to bury myself in my studio (aka the storeroom in the basement).
This is one of a couple things I have in the works. It's tissue paper, used tea bags and image transfer using matte medium. Each piece is 4" x 6". I have another tin can garden in the works too.
