Well, lets see.
*Making a commitment to the shop owner to show my work at a certain date, motivates me to continue to develop my skills and imagery, to expand my thinking about the work.
*It forces me to focus my mind and to be disciplined.
*It gives me a chance to celebrate my work with my friends, and to show them what I've been doing.
*It establishes my reputation as an artist in the community.
*It builds my inventory of work I can then photograph for cards or to sell as prints.
*It introduces my work to new people.
And I just MAY sell enough to buy materials for the next show!
