What you need
Staple Gun (with ¼ staples)
work area (Large TechShop table)
Extra pair of hand (if need be)
Canvas Stretching Pliers (if you want)
Once you have your frame built, you need to stretch the canvas. I used per gesso canvas, which I do not recommend. With the per gesso canvas you can really get a good pull.
Step 1: The Canvas
Tear your canvas about 3 inches larger on all four sides. Lay your canvas down (gesso side down) on a clean work area. TechShop has large work table that work out wonderful for stretching your canvas and the area is nice and clean and that is not on the ground. Put the frame on top of the canvas, with the top of the frame point down.
