What do I do if my canvas loosens?What do I do if my canvas loosens?
If your canvas loosens after you've made your painting, our stretchers are able to deal with that situation. The mitered double mortise and tenon joinery - held together with friction
- can be expanded using the included keys. These keys go into the small square openings in the joinery of the bars and braces and can be tapped with a hammer to spread the joint, thus tightening the

A keyable stretcher allows you to re-tension your canvas. All the joints of our keyable stretchers are expandable with the supplied wedges, or keys. When needed, the keys are tapped
into the joints, causing them to expand and thus tighten the canvas. We find this type of traditional joinery to be superior when compared with various other mechanisms used to re-tension canvas.
Unlike mass produced stretcher bars, our bars are handcrafted to be straight. The mortise and tenon joinery is designed with substantial thickness, which adds strength to the finished stretcher and,
most importantly, allows the stretcher to retain its strength when the joints are expanded.
kind of wood do you use? Are your products sustainable?What kind of wood do you use? Are your products
We use poplar (Liriodendron tulipifera L.) which is a hardwood. Poplar is a bit stronger than pine, a bit harder than pine, but weighs about the same. Poplar also has great dimensional
stability, as evidenced by its use for interior casework in fine furniture for centuries. Poplar grows on the East coast, relatively close to our shop, which cuts down on the distance the wood has to
travel for its end use. It is a relatively fast-growing tree that grows tall and straight. Poplar's relative proximity to our shop make it an environmentally friendly choice for us and its fast
growth make it the best choice as a renewable resource.

All wood moves with changes in humidity, regardless of the species of wood or where it has come from. The trick is to find a wood with the qualities that are needed. Species selection
is the first important step in making a stable object. The next important step is wood selection within that species, which involves selecting wood with straight and stable grain.
At DoubWorks we use a species of wood that has minimal seasonal movement yet still has the other characteristics that are needed for a stretcher bar - strength and bending resistance. If a stretcher
bar has a spiral to its grain the expansion and contraction of the wood due to changing humidity can cause the bar to twist. This twisting is the reason for what is referred to as "warping," where
three corners of the frame touch the wall and one corner pulls away from the wall.
This particular problem is not caused by a lack of internal bracing. The primary function of internal bracing is to resist bending of the bar due to the tension of the canvas. Bending can also occur
due to the seasonal movement issue mentioned above. For example, wood grain swirling around a knot in the middle of a bar can cause it to bend with humidity changes. So is it possible for DoubWorks
stretchers to warp? The answer is yes, it's possible for any wood to warp, but due to our care in species and grain selection and our in-house milling process that produces dead-straight bars, our
stretcher bars are much less likely to move.
