39x78 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 2:1 Domino Proportion - 39x78 Size

An intriguing Domino size!

The 2:1 aspect ratio, that we call the domino proportion, also offers a unique canvas for artists to play with the perception of space and depth within their compositions. The elongated format allows for the inclusion of foreground, middle ground, and background elements, creating a sense of distance and scale that draws the viewer's eye into the artwork. This aspect ratio has been used by artists throughout history, from ancient Egyptian tomb paintings to Renaissance frescoes to contemporary photography. Its versatility and timelessness make it a classic choice for artists seeking to create dynamic and engaging compositions.

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.

Our Ecosystem Depends on Healthy Forests

Forests play a vital role in our planet's ecosystem. They absorb carbon dioxide, filter air and water, and provide habitat for countless species of plants and animals. By using sustainably sourced lumber, we can help to protect these important ecosystems and ensure that they continue to provide these valuable services for generations to come.

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.

49x88 is the Canvas Size Needed for this 39x78 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.

I find happiness when the sun paints shadows on the earth. ♦ Paul Gauguin

Paul Gauguin's life was characterized by his constant search for beauty, not just in the celebrated or obvious, but in the subtle interplay of light and shadow, the everyday and the overlooked. His time in places like Tahiti was not merely a quest for vibrant colors but also for the contrasting shadows, the unseen narratives, and the silent whispers of nature.

In our art careers, it is easy to get caught up chasing the dazzling, the spectacular, or the popular. But Gauguin's sentiment reminds us that sometimes, true happiness and artistic fulfillment can be found in the quieter moments, the interplay of light and dark, and the stories that shadows tell. We are often drawn to the luminosity of success and recognition, but there's a profound beauty in the spaces in between, waiting for us to discover and cherish.
