I don't really want to discuss pricing here, but there isn't a whole lot of difference in the actual stretching process.
I always try to staple on the back rather than the sides if there is enough canvas even if the canvas is going into a frame.
That way if there are any changes down the road, there are no staple holes in the side near the canvas image.
It doesn't take any more effort to do it this way and we do lots of them.
The only difference is doing a gallery wrap on tall strainers if the customer requests this.
1" tall, 2" tall, 2 1/2" tall, 3" tall or whatever.
Then the price goes up, mainly for the strainer stock, and our Lifesaver POS has the prices for all of these based on the height of the strainer.
Thanks for the info. I understand that there is some anxiety about discussing pricing on the Grumble but I often see framers comparing their retail pricing which is what I was looking for. A customer brought in an 18 x 24 canvas for stretching and was quoted more than twice what we charge at another shop. I was wondering if we don't charge enough?
Ditto what Neil said.
Gallery wrapped canvas usually involves deeper stretcher stock, so the price goes up accordingly, but labor is generally the same either way. Of course, the price also goes up if we need more time to work with thin borders on the canvas, or if strip-lining or other repairs are necessary.
If you are unsure about your pricing, apply your hourly Shop Labor Rate per minute to the time required for the work, then add the cost of materials, and reasonable profit.
