Something I'd like to share, being a fair reader for a number of years. ..and this is not directed at any one person, just something I'd like to share.
When doing fairs or hanging out at venues ... You gotta do your time. You gotta show up! People need to see you, over and over.
When you do get a reading, or three, get the sitter's email address, so you can let them know about other events you will be participating in.
Sometimes it's easy to think, "Oh yeah, I'll take my deck, sit at a table and make a ton of money!" It really doesn't work that way. ...and it takes time to build a clientele. Stick with it...and in time you will have "regulars."
