Solid Wood is Archival - Finger Jointed Wood is Not

We only use Solid Wood to build our Stretcher Bars because a solid piece of wood will last indefinitely. When we speak of archival value, it's not just the paint you use and the quality of your canvas and ground, even the wood choices manufacturers make are part of the archival process.

The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.

As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.

Forests need People, and People Need Forests

Using lumber from sustainably managed forests is a way to support the health and well-being of our planet and its inhabitants. By choosing products made with sustainably sourced lumber, we can help to protect the environment, support local communities, and ensure a sustainable future for generations to come.

22x61 is the Canvas Size Needed for this 12x51 Frame

Please note that you will need a canvas that is at least 10 Inches larger than the actual frame size to ensure proper stretching. This will provide ample material to stretch the canvas and attach it to the back of the frame. If you prefer to attach the canvas from the edge of the stretcher frame, you can reduce the size of your canvas by approximately 3/4" all the way around the frame. This will allow you to paint on the edge of the canvas and hang your artwork without needing a separate picture frame. And, if you ever need to remove the canvas from the frame and re-attach it, you'll have enough material to do that too.

Tight'n'Up™ Liquid Canvas Retensioner

One of our most appreciated products helps make your canvas tighter! Stretching a canvas tightly can be a challenge. Our Frame Kits include the Corner and Brace Keys that you will need to add tension, but Tight'n'Up™ Liquid Canvas Re-Tensioner is a way that you can use to add tension to the canvas without needed to use the keys. It canvas be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets. Recommended for acrylic primed cotton or linen canvas. We do not recommend it for oil primed canvas because there are simply too many different types of oil primed canvas, but used conservatively at your own risk, it will tension any canvas.

A picture, before being a battle horse, a nude woman, or some anecdote, is essentially a flat surface covered with colors assembled in a certain order. ♦ Nicolas de Staël

Nicolas de Staël's perspective on art echoes the raw essence of what painting is at its foundational level. By stripping away the narrative and the representational aspects, he brings attention to the bare bones of a canvas: color and arrangement. It's a refreshing reminder, especially in a world that often prioritizes the stories and subjects over the medium itself. De Staël challenges us to see beyond the immediacy of subject matter and delve deeper into the nuances of the art form.

Understanding this concept can be transformative. We often pour our energy into perfecting the representation, while the essenceÑthe heart and soul of the artÑlies in the orchestration of color, texture, and space. By honing in on these basic elements, we can uncover fresh dimensions and explore novel avenues in our work. Nicolas de Staël's words serve as a beacon, inviting us to reevaluate our approach and to cherish the raw, tactile, and intrinsic qualities of our craft.
