I don't mean to revive an old thread, but I had also been on the search for freezer paper in Canada, and couldn't find any, until today, behold, freezer paper! I immediately thought of this thread as I had done a search before on the boards to see if anyone knew where to buy the paper.
Some weeks ago, I had searched many stores (Wal-Mart, Sobeys, Jean-Coutu, Shoppers Drug Mart) and came up empty. I'm in eastern Canada for reference. While doing groceries today, I found some. I was at a different Sobeys than the one from before I had looked in.
Here's what it looks like:
I picked it up, and wondered, "is this really it?" It said freezer paper after all, but it also said "plastic coated" beneath that.
And then, the box answered my question. On the top of the box, it says:
"Make non-slip stencils. Temporarily adhere the plastic side to fabric with a hot, dry iron. Peel off stencil when paint dries."
Maybe I got lucky to find some. Actually, maybe I should also go back and buy another 2 boxes
