While reading my morning paper, I came across an advertisement that 1) The Goodman Studio has a glass blowing demo today; 2) there is an annual sale happening; and 3) the handmade-in-Toronto glassmaking studio is only 15 minutes away from my home in an industrial area.

 

The Goodman Studio doesn't sell direct to the public and the workshop isn't open to the public normally, so I grabbed my camera to have a look.
