Canvas Phobia

As a newbie artist I have a phobia of canvas. Something about putting the brush to the bright white canvas and making a permanent mark makes me nervous. So nervous that I hold myself back. I have probably only made 2 large canvas paintings that I love, maybe 1 more that I like. The rest turn out not so good. Somehow my vision and small sketches when put on the big canvas don't turn out like I want them too. My current solution is to start my canvas like my sketches.

I do a technique when I sketch sometimes where I use a sharpie. The idea is that everything that goes down on paper is permanent. It forces you to slow down and think about every single stroke of your pen. You start somewhere on your paper and continue drawing until the paper is full or until you are satisfied with the drawing. For some reason I love making these and they almost always turn out well.

I am thinking about starting my next canvas like I start my sketches. I am hoping that this mentality will help my inner creativity loosen up somehow, and kick my phobia of canvases.

Anyone else have a phobia of canvas... or is it just me?
