I don't know where in Ontario you are, but if you are near a Lens Mill Outlet go and take a look. The largest is in Guelph/Cambridge, and a couple of smaller ones are Brantford, and Stoney Creek. Google their website, they may even mail to you. Fabricland knows there are fewer stores we can go to for fabric and tend to be higher on other than basic cotton.
Good luck from Oakville.
