Texturing Canvas

I bought 14 inexpensive larger canvas today to texture. Why? Randy Blasquez did a beautiful painting demonstration and talked to us about how she textured her linen canvas. Now I want to experiment with texture,  too. So I brought out my big bucket of gesso to cover the inexpensive canvas.  I want to be sure the Golden Acrylic Gel I want to use will stick properly. I read where if you used cheap canvas that isn't properly primed it might flake.
