Art Fair on the Square is an annual event that I look forward to every summer in Madison, although I often feel like a little kid in the glassware section of the department store where I can look but I can't touch (or afford).
Honestly, this event is more a display of artwork than an opportunity for art enthusiasts to purchase pieces. The prices are way out of the range of a casual art collector... There are a few artists who make cute knickknacks (tea bag holders, micro bowls, etc.) that are a little more affordable, but still nothing that I would realistically drop $10-20 on.
Even then, I love seeing the diversity of the artists and the mediums they choose to use to convey their message. I amused myself by trying to pick out the pieces that I thought would be chosen for the Epic campus. :P
It's also just nice to see all of Madison out and about wandering around the Capitol. That's something I always look forward to during all of these city-wide events!
Tip: The farmer's market still takes place on the Saturday of the art fair! The selection is sparse, and their location is different (most likely pushed off into a side street), but keep an eye out for the fresh fruit and veggie stands!! They will be there!
