What adhesive are you using to stick the newsprint to the stretched canvas? Tried the same, but the stuff I used just peeled right off. Great work as always, man.
I use some stuff called Mod Podge. Basically it's thick all purpose glue. Scratch that, I use A LOT of mod podge. I coat the area of a canvas, then lay down a layer of newsprint and while it's still wet I'll squeegee out any air bubbles. Then I'll let that area dry before going on to another area. I usually will work on multiple canvases at once, like a conveyor line. That way it gives each area time to dry while I'm working on a different canvas.
