I have been to Quilt Canada and to be honest, I would rather go to local quilts shows. Be prepared to do a lot of walking and take bottled water with you, some ladies had (a lot) had their own lunches with them Another thing to do is take a wheeled carrier.makes it easier to carry your purchases.
Yes, there is a variety of fabrics, you will find Lens Mills there too. All in all prices vary from booth to booth..
Go, have fun and enjoy the day..
