Professional artists, such as those who might specialise in pet portraits, will want to reduce the cost of their materials as much as possible. Buying ready made canvas, is an added expense that the artist can probably do without, a much better idea is to buy the component parts and make up your own canvases as and when you need them. You’ll need a roll of primed or unprimed canvas, stretcher bars and upholsterers tacks or staple gun.
1. Fit the stretcher bars together to form the frame. Place this on the canvas, beveled side down, and cut around it leaving an extra 2 inches on all sides.
2. Start with a long side, fold the overlap onto the back of the bar and tack it in place, starting at the centre and working out to each end, tacking every 2 or 3 inches. Leave the canvas unfixed for the last 2 inches of the bar at both ends.
3. Go to the opposite side and pull the canvas over the bar making it as taut as possible (you can get special pliers to help you for this job). Whilst keeping it taut, tack the canvas to the bar, starting at the centre and working along to each end, keeping it taut as you tack. Again, leave the last 2 inches of the bar unfixed at each end.
4. Repeat steps 2 and three for the shorter sides.
5. Take one of the loose corners of canvas and fold it over so that the point is in line with the joint of the stretchers and place it flat against the bars. Whilst holding this in place, take the fold of canvas to the left of the corner and place it on top of the corner, then take the right fold and place this on to of the left. All the time keeping the canvas as taut as possible. A single tack or staple should be enough to hold all this in place.
6. Repeat this for each corner then use the wedges to tighten the canvas if required.
It’s a fairly simple process, but one that requires experience to create a very tight canvas, with no creases. With practice though, you’ll be able to do it without thinking and the envy of any good pet portrait artist.
