My favourites are Sew Sisters in Ontario. Nice selection of fabrics and very good service. They are great and often have very nice fabrics in their clearance items. Hamels fabrics is another one I purchase from frequently. For many other quilting, sewing and bag making items, Stitch In The Ditch in Kelowna is great. I love their selection, prices and very fast service. I often purchase from Missouri Star but have the order sent to a box across the line and pick it up there. I have never been charged anything extra so far when crossing the border. I believe that many Canadian quilters also order from Connecting Threads. I'm very tempted and will likely try them very soon.
