This video begins by showing what a folding painting canvas looks like and what the final stretched canvas should look like. The first step shown is to make sure the bars are measured and marked with a simple A and B for easy measurement recall. After a wood frame is added over the canvas you must fold the material over the back of the wood and nail in place. Once the canvas is nailed to the frame you must add A, B, C and D markings to continue proper alignment procedure. The last step shown is to pinch the material and pull on all four corners of the canvas to finish proper stretching of the material.
