There are many components of a successful art show besides simply creating the art work. Of course, the quality of each piece is important; probably the most important factor. However, of near equal significance is the continuity of theme, color, and subject of the paintings. So, I test this factor by lining up the paintings, one next to the other, to give me a sense of whether they work together.
Promotion is also a major step in preparing for the show. Figuring out the most efficient way to timely contact the largest number of people to get the word out is a challenge. Social media is a wonderful aid as are good old fashioned publicity handouts.
Finally, creating an inviting and comfortable atmosphere is key. The right food, refreshments and music are important.
I enjoy the whole process but, it can keep me up at night, fretting over the details.
