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

The concept of sustainability presupposes a comprehensive engagement of individuals in the art and science of forest stewardship, both in the present and for the well-being of generations to come. Humanity undoubtedly extracts wood from forests to supplement our needs, but they also play a crucial role in bestowing diligent care upon these ecosystems. This stewardship encompasses not only the responsible harvesting of forest resources but also extends to the safeguarding of clean water sources, the preservation of wildlife and their native habitats, and the mitigation of potential threats like erosion, fires, and diseases that could otherwise lead to untimely degradation of these precious woodlands.

Masterpiece® uses only lumber harvested from responsibly and sustainably managed timberlands.

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.

29x59 is the Canvas Size Needed for this 21x51 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.

Normality is a paved road: It's comfortable to walk, but no flowers grow on it. ♦ Vincent Van Gogh

Whose life and art were anything but conventional, Vincent Van Gogh often found beauty in the tumultuous and the misunderstood. His sentiment regarding the allure and limitations of normality sheds light on his intrinsic drive to tread off the well-beaten path. To Van Gogh, the allure of the unknown, with all its struggles and uncertainties, held a beauty that the familiar simply couldn't match. His unconventional path, marked by bouts of passion, despair, and brilliance, was mirrored in his artworks, which often portrayed the raw intensity of nature and human emotion.

It is a powerful reminder for artists everywhere. The easy path, the one most traveled, might offer comfort and predictability, but it's the less-trodden trails that challenge us, pushing us to grow and evolve. Just as flowers find their way through cracks and bloom in the most unexpected places, our creativity often shines brightest when nurtured outside the confines of the ordinary. We are prompted to think differently, to take risks, and to discover new facets of our artistry. The world is vast, filled with infinite possibilities; it beckons us to explore, to step outside our comfort zones, and to let our imaginations roam free.
