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.

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.

23x28 is the Canvas Size Needed for this 13x18 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.

You will find the spirit of Caesar in this soul of a woman. ♦ Artemisia Gentileschi

Artemisia Gentileschi, one of the most accomplished painters of her generation, uttered these powerful words as a testament to her resilience, strength, and ambition. Living in the 17th century, a period rife with patriarchal constraints, she was not merely a spectator but a fierce combatant against gendered prejudices. With this statement, she equates her spirit to that of Caesar, a leader whose name became synonymous with power, authority, and triumph.

This assertion underlines the universal human potential that transcends the boundaries of gender. When we approach our canvas, we carry with us not just our skill set, but our histories, our battles, and our victories. The very essence of creation is imbued with our personal narratives. Our creations can be as mighty as the most powerful figures in history, echoing sentiments that resound through time. Gentileschi's masterful works were her battlefield, her brush the sword with which she carved out her legacy, standing tall among her male contemporaries.

She challenges not just her peers but all of us, asserting that indomitable spirit is not the dominion of any one gender or any specific role. It's a clarion call for artists to recognize and harness their inherent power. Regardless of the societal norms or constraints, we can paint our personal narratives on history's canvas, ensuring that our spirit, like Caesar's, and Artemisia's, becomes legendary.
