Stretching my own canvas...

I love stretching my own canvases...I can pick any size stretcher bars and make a square or rectangle. I have chosen 4 - 24" bars for this canvas. The bars are 3/4" deep so I add 1" plus and extra 1" for wrapping to each side...(24 +1+1+1+1) . so I will cut a piece of canvas (I use 100% cotton canvas pre-primed), 28"x28". I lay towels down so the canvas or table surface isn't scratched during assembly. Tomorrow I will show how to start attaching the canvas to the bars.
