I paint pet portraits on commission. At an art fair I wouldn't have anything to sell that day. Does anyone have any advice for me? I just participated in my first fair, an Art Walk in Austin, Texas. I brought framed copies of my portraits, talked to all the people, handed out flyers and business cards and collected email addresses, and even had a water bowl and dog treats. What else can I do to encourage business when everything I paint is individually commissioned and requires action from prospective buyers? Thanks for any help!
