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.

Sustainability Fights Against Climate-Change

Sustainable forestry practices are an important tool in the fight against climate change. By using lumber from sustainably managed forests in our products, we can help to reduce the carbon footprint of our business and support the health of the planet. It's a win-win for everyone involved.

20x47 is the Canvas Size Needed for this 12x39 Frame

Please note that you will need a canvas that is at least 8 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.

I took a walk in the woods and came out taller than the trees. ♦ Henry David Thoreau

Henry David Thoreau, the revered American transcendentalist, found profound wisdom in the natural world. Known for his two-year sojourn at Walden Pond, Thoreau immersed himself in nature, finding there both solace and insight. This quote captures the essence of his philosophy: that nature has the power to rejuvenate, inspire, and elevate the human spirit.

For us, nature can serve as a boundless source of inspiration. The textures of leaves, the colors of sunsets, the vastness of landscapes Ð they all beckon to be captured on canvas. More than just a visual feast, the great outdoors offers a mental and spiritual retreat. A walk in the woods isn't just about physical movement but a journey into oneself. Amid the trees and trails, we can reflect, find clarity, and emerge with a heightened sense of purpose. In our artistic paths, such moments of introspection can shape our perspective, refining our techniques and visions. Just as Thoreau felt taller after his woodland walk, we too can feel enlarged, our creative spirits elevated, every time we seek inspiration in nature's embrace.
