This Canson Canva-Paper is fairly stiff (136 lb paper) and has "the look and feel" of cotton canvas imprinted on the paper. I like using this paper because of the stiffness and once I've completed a painting I can leave it on a display easel without the paper sagging or curling.
Before I start to paint, I mount the Canva-Paper on a hardboard. Any firm/stiff board can be used for the backing. To keep the paper from moving around, I tape the paper down using blue painter's tape. This tape also helps where I can freely paint to the edges and not get any paint on the hardboard backing. As you can see, I've used this painter's tape before on another painting project. I just turned the tape around so the clean side is touching the new project.
After a few days and when the painting is dry to touch, I gently peel off the blue tape. I can then leave the painting on a display easel to dry further.
Another "canvas pad" that I've purchased, but not have used yet is Fredrix. I can't call this paper as it actually feels like true cotton canvas. When I lifted the first sheet on the pad, it felt like cloth. The sheets are not stiff, but flexible. I guess I should not have been that surprised as the word "paper" is not mentioned/advertised on the pad. Instead, it reads "genuine artist canvas". I purchased a huge 16x20 pad at my local Michael's (w/coupon) and had to literally hand cut a canvas sheet down to four 8x10s. Sharp scissors worked nicely.
Here's paper cutter similar to the one I use to cut my Canson Canva-Paper:
