Connecting Threads has a special on this round ruler foot to replace almost any domestic machine open toed foot in order to FMQ with rulers. They would not ship this product to Canada as it comes directly from Australia. I hunted down the web site and ordered the ruler foot directly. With the $exchange almost par with the Canadian $ they shipped the foot for about only $25 more than if I had I ordered it from CT. A quilt shop in BC is offering it for $99 Worth a peak if your interested.
