65x70 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 14:13 Near Square Proportion - 65x70 Size

The 14:13 aspect ratio is one of our intriguing near square proportions, which offers subtle asymmetry. Unlike a perfect square, which can sometimes feel static, a near-square ratio like 14:13 provides a slight horizontal or vertical stretch that introduces just enough imbalance to make compositions feel dynamic while still being contained and compact. Create an unusual tension between symmetry and asymmetry. This subtle variation in the dimensions might work well for portraits, still life, or minimalist compositions, where balance and proportion are important but don’t need the formality of a perfect square.

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.

Sustainable Forests - A Precious Natural Resource

The air that we breathe depends upon our healthy forests the world over. For this reason, we only use lumber from the sustainable forests of the Pacific Northwest, so we can guarantee that our nation's precious natural timber resources are available for future generations.

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.

75x80 is the Canvas Size Needed for this 65x70 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.

The world is but a canvas to our imagination. ♦ Henry David Thoreau

Henry David Thoreau, a master of observing the world and reflecting upon it, leaves behind a legacy of wisdom. From his tranquil days spent at Walden Pond to his passionate advocacy for civil liberties, Thoreau consistently demonstrated how one's environment can be transformed through the lens of imagination. In viewing the world as a canvas, Thoreau isn't just talking about passive observation but active creation, a call to action for every artist and thinker.

We can find ourselves sometimes limited by our surroundings, yet Thoreau's perspective invites us to see beyond the obvious, urging us to seek the potential in every scene, subject, and moment. The mundanities of life become the subjects of poignant masterpieces, and the ordinary morphs into the extraordinary. By taking to heart Thoreau's insight, we not only enrich our artistry but also enrich our lives, creating a world filled with endless possibilities and unlimited horizons.
