No, they're not canvas. They're cotton quilting fabrics, and they are BY a company called Canvas.
Canvas is a new division of Benartex. And apparently they will be specializing in novelty fabrics, because their head designer *used* to be the lead designer at Timeless Treasures.
You can see the fabrics on Checker Distributor's website here:

(I figured if there's a new fabric company out there, you would all want to know about it! )
