No, however it is strongly recommended. Again, you are selling your own works. It is best if you, the artist, are engaging with your audience and working to gain more interest for yourself. If you are not able to make one of the days, both days, or need to leave early/show up late, we ask that your works each have a label with your name and contact info, title of piece, and price on them. This way, interested buyers can get in touch with you.
