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 Promotes Social Well-Being
The forests of the world are a precious resource that must be protected for future generations. By using lumber from sustainably managed forests in our products, we can help to ensure that these valuable resources are preserved and protected. This is not only important for the environment, but also for the social and economic well-being of the communities that rely on these forests for their livelihoods.
Specially Dried and Heat Treated Lumber
Our wood is handpicked from a curated group of environmentally responsible lumber mills in the Pacific Northwest. By adhering to our precise drying and heat-treatment standards, these mills produce lumber with nearly half the moisture you'd find in common home improvement outlets or lumber yards. This meticulous process not only enhances the wood's strengthÑminimizing risks of cracks, splits, or bendsÑbut also elevates its dimensional stability. Such quality, despite its premium, is paramount in creating professional canvases designed to uphold the sanctity of your cherished art throughout the years.
31x97 is the Canvas Size Needed for this 21x87 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.

To live is to suffer, to survive is to find some meaning in the suffering.
♦ Friedrich Nietzsche
Friedrich Nietzsche, the formidable German philosopher, was no stranger to personal strife. Beset by health issues and emotional torments throughout his life, Nietzsche's works often explored the nature of existence, pain, and the human condition. His assertion here is not merely an observation but an insight into the resiliency of the human spirit.
Suffering often becomes an inextricable part of our creative process. It's through the crucible of personal challenges that many of us find the depth and substance to translate our emotions into art. But Nietzsche urges us not just to endure but to find meaning in our struggles. It's a call to transform our pains, doubts, and hardships into something transcendent. As we grapple with our own challenges, art provides a medium to communicate, reflect, and even heal. By finding meaning in suffering, we not only survive but flourish, leaving an indelible mark on the canvas of life.
Creativity, the silent force beckoning you, finds its voice here. Harmonize your artistic process with these indelible words and meaning by Friedrich Nietzsche, and with our unique portrayal of a self portrait to inspire an enhanced melody in your art. Go make your music on canvas!
