STRETCHING YOUR CANVAS ON A WOODEN, STRETCHER BAR FRAME
Your rolled canvas will be laid over a pine stretcher bar frame, the outer edge of which coincides with the part of the artwork you want to display (the front), pulled very tightly, and stapled to the back. Stretcher bars are available in a variety of widths -the larger the dimensions of your canvas, the wider the frame must be to support the final weight without bowing or breaking.
Stretcher bars come in many different depths as well (the width of the drop edge). Generally, larger canvases look good on thicker frames, while smaller canvases look better on thinner frames, but the choice in yours. In some cases, however, your selection may be limited by your canvas.
There must be enough surrounding, blank or unneeded canvas (that is not going to show on the front) to wrap around the stretcher bar frame to the back. For instance, if you have only 3cm of excess on each side, it is not advisable to mount your canvas on 2.5cm bars - there is too little canvas to wrap all the way around and therefore it is extremely difficult for the framer to stretch the canvas tight enough. This can result in dimples and valleys in your canvas, which will only worsen as time goes on.
The more excess canvas around your artwork, the better. Too much can always be cut off once the piece is mounted on the stretcher bar frame, but if there's not enough, more cannot be added on.
If your canvas has plenty of excess, you need to consider what look you would like to display. The stretcher bar depth measurement translates to how far the face of your canvas will protrude out from the wall.
Once you have determined the depth you want, our framer will create a custom frame especially for your canvas. This sturdy, lasting frame will support and display your piece for generations.
