Almost forgot...I had an amazing discover at Dollarama in the summer months and only bought 3 at the time. Once I realized how great they were, I returned only to discover they were sold out. What is the product? multipurpose Craft Mats. This heavy-duty plastic is great for templates - not too hard to cut and substantial enough to trace around without shifting.
I was surprised to see them back in the store this week. They come in 3 colours (purple, lime and blue) and the dimensions are 51cm by 43cm. Here in Huntsville they are in the same aisle as the craft supplies....good luck and buy lots - you might never see them again!
