If the fall fair isn't your thing, my wife is organizing a big craft show in conjunction with Etsy this weekend. It's in Hamilton at the Steam and Technology Museum (National Historic site) and has over 60 vendors; lots of talented artists and crafts people from across the province will be selling in addition to a handful of food vendors. Check it out if you're into unique handmade stuff. The last show in April was a huge success, lots of really nice stuff for sale.
