3D™ Pro 2.5 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 Inhale and Exhale

The world's forests are essential to human survival. Forests inhale carbon dioxide for the earth, and exhale oxygen essential for life. When we speak of the sustainable forest strategy of ensuring that more timber will exist in the same forest land than exists today, this is the only viable plan for the future of humanity. For this reason, we use only lumber from the sustainable forests of Oregon, Washington, and California, where there’s more standing timber today than last century!

24x29 is the Canvas Size Needed for this 16x21 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.

Orphism is the art of painting new structures with elements that have not been borrowed from the visual sphere, but had been created entirely by the artist. ♦ Robert Delaunay

Robert Delaunay, an innovator in the realm of art, firmly believed in the potency of artistic originality. When he introduced the world to Orphism, it wasn't just a new art movement; it was an invitation to artists to break free from the traditional constraints and find pure, unadulterated inspiration from within. The very essence of Orphism lies in the ability of artists to look beyond the observed world, reaching into the depths of their imagination to create something entirely new. For artists, the challenge is to tap into our own reservoir of creativity, pulling from emotions, experiences, and unique perspectives.

This groundbreaking perspective Delaunay offered serves as a reminder that we, in our pursuit of artistic mastery, need not be limited by the physical world or previously established norms. In fact, the beauty of art lies in its boundlessness. It's an open field, where experimentation and innovation are not just encouraged but celebrated. And as artists, we should continually seek that realm of endless possibility, shaping our path with strokes of imagination that belong solely to us.
