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.

Sustainably Managed Forests

We use lumber grown in the sustainable forests of the Oregon, Washington, and California, where there’s more standing timber today than last century! Our forests purify the air, provide oxygen, and reduce global warming. More trees are needed on this planet, not fewer. Therefore, we use lumber grown in responsibly managed forests, so future generations can benefit from our collective responsible actions today.

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.

91x100 is the Canvas Size Needed for this 81x90 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.

One resolves to be a painter; once one is, one paints—after having, naturally, tested all the techniques. ♦ Paul Gauguin

Paul Gauguin's life was characterized by an innate restlessness, a continuous quest for meaning, and an unyielding commitment to his artistic vision. This sentiment encapsulates the essence of Gauguin's artistic evolution and serves as a reminder of the journey that every artist must undertake. The determination to be a painter, the unwavering belief in oneself, is only the beginning.

For many artists, the path to mastery is paved with countless hours of experimentation and self-discovery. We explore various mediums, dabble in different styles, and immerse ourselves in a myriad of techniques. This process is not simply about acquiring skills but is more profoundly about understanding our own unique voice and how best to express it. Gauguin himself transitioned from being a stockbroker to becoming one of the most influential Post-Impressionist painters. His art evolved, influenced by his travels, experiences, and incessant exploration of various artistic traditions and methods.

We recognize that the pursuit of art is as much about introspection as it is about external expression. The canvas becomes a reflection of our inner world, shaped by the techniques we've learned and the experiences we've lived. Gauguin's words serve as an affirmation: to first commit to the calling, to immerse oneself in the vast ocean of artistic possibilities, and then, with newfound wisdom, to paint with authenticity and passion.
