My canvas is an 8 inch by 10 inch stretched canvas and the frame is a ready made, deep set frame with glass and a mat. I start by taking out the frame points with some pliers and taking out the glass and mat, which I'll use in another project.
The canvas sits into the frame then I drive framing points in with this tool that has an official name but I call it a point shooter. I put in two points per side.
Then I apply strips of acid free framing double sided tape to all four sides of the frame, otherwise known as ATG. Don't worry about going over the edges because it rubs off easily.
For the backing, I cut out a piece of brown packing paper a bit larger than I'll need. I begin by pressing down on the paper at the top edge of the back of the frame - I like using the longer side first. Then I pull the paper taught down to the bottom edge in the center first, then working out towards the left and the right. I do the same on the sides, starting in the center, working your way out (much like stapling a canvas onto a frame when stretching a canvas). I use my thumb and index finger to burnish the paper over the edge.
For the next stage, there is a cutting tool for this job available so you don't need to handle a blade directly but since I was trained this way when I was 16, this is the way I still like to do it today. I hold the blade between the meat of my thumb and the tip of my index finger, so the bottom of my thumb can be a constant gauge along the side of the frame creating a straight line all the way down. Again, I wouldn't recommend this technique, it's just how I do it. You can use a straight edge/ruler and a box cutter knife for similar results. In the last picture I show how you often get residue of the ATG once you've peeled away the paper. This rubs off easily and balls together like rubber cement when you rub the edge with your thumb.
Next up, I measure about a third of the way down the frame and make a small hole with an awl on either side. I get the screw eye started by hand then turn it the rest of the way into place using the awl.
Picture framing wire goes through the screw eye, pulled back, looped under and over the wire, then woven through the eye again. The wire then gets twisted around several times to really lock it into place (that wire isn't going anywhere now), cut and finished with a bit of tape just so you don't leave any raw pieces of wire that can poke and cut you or the handler of the piece. Pull taught but not TIGHT and do the same on the other side.
Add some bumpons to the bottom so it won't scuff up the wall and voila - you've got a framed canvas!(If you're framing an oil painting, cut a hole in the backing paper so the canvas can breathe - this piece it is fine as it is).
I hope you enjoyed this simple tutorial of sorts. I'm looking forward to working on more framing projects now that I have the space. If anyone has any picture framing questions, let me know and I'll try my best to answer them. 10+ years in the business and most of the tricks of the trade are still fresh in my mind.
