Carrie Hayes, a really good corset designer in Toronto, is teaching a corset making class starting in May. The class costs $375, which is'nt bad, as you gain all the knowledge to make tons of corsets.

Ooooh... I so want to go. I can't do the summer session (I'd miss classes because of faire!) but I'm SO going to try for the fall session!
