3D™ Pro 3.5 Stretcher Bar • 1/2" Canvas Clearance

1/2" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretcher Bar.

• 1.25" wide Stretcher Bar
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

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.

Sustainable Forests Ensure More Wood for Communities

Using lumber from sustainably managed forests is not only the responsible thing to do, it's also a way to ensure that the wood products we rely on continue to be available in the future. By supporting sustainable forestry practices, we can help to ensure a steady supply of wood products while also protecting the environment and supporting local communities.

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 strength—minimizing risks of cracks, splits, or bends—but 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.

28x97 is the Canvas Size Needed for this 18x87 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.

I cannot speak of Diego as my husband because that term, when applied to him, is an absurdity. He never has been, nor will he ever be, anybody's husband. I also cannot speak of him as my lover because to me, he transcends by far the domain of sex. And if I attempt to speak of him purely, as a soul, I shall only end up by painting my own emotions. ♦ Frida Kahlo

The iconic Mexican painter known for her bold and surreal self-portraits, Frida Kahlo shared a complex relationship with the renowned artist Diego Rivera. Their bond, tumultuous yet intensely passionate, defied conventions and often blurred the lines of love, camaraderie, and artistic collaboration. Kahlo's reflections on Diego speak to the depths of human connections that can't be encapsulated by societal labels. In the realm of art, where emotions are laid bare on canvas, Frida's words evoke the challenge of capturing the essence of another while still staying true to oneself.

For many artists, the canvas becomes a mirror, reflecting their innermost feelings and vulnerabilities. It's a delicate dance, to draw inspiration from others without losing oneself in the process. Just as Frida grappled with defining her relationship with Diego in words, artists often find it challenging to translate the intricacies of human relationships into visual representations. Yet, in that challenge lies the beauty of art. The act of creating allows us to delve deep into our emotions, questioning, exploring, and ultimately expressing what words often cannot. Through our creations, we not only share a part of our soul with the world but also embark on a path of introspection and self-discovery.
