As an artist and gallery owner ( www.artistsonmainmt.com), I have found that stories sell artwork. Viewers want to know about the artist and why they created the work.
I live in Montana with many tourists visiting our area to fly fish, see the wildlife, visit Yellowstone National Park, and hear our stories. My Cliff Swallow series evolved from the swooping swallows that inhabit an area along the Madison River called the Palisades. With a short story about our area swallows attached to each piece, sales increased.
Think about including a short story with your pieces,
