True 3:1 Panorama Proportion - 40x120 Size

This unique 40x120 is actually a fairly common 3:1 proportion used in art and cinema.

The 3:1 Panorama a proportion is preferred by many artists who require a super wide compositional format. Of course, this proportion is popularized by photographers and cinematographers, for ultra landscape and wide angled imagery that creates a sense of scope and grandeur in a scene, like cityscapes, ocean and mountain scenes, and scenes with expansive horizons. It is described as a polyomino proportion on the order of 3 or triple-square proportion. There are several common Panorama sizes in this 3:1 aspect ratio that you will recognize, and some are intriguing custom sizes, as well.

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.

What is Sustainable Forestry?

To a forester, the term "sustainable" could mean exercising industry adopted forestry practices to maintain a forest indefinitely. To a logger, the process of proper care for the trees remaining after a harvest. To a landowner, their interest may lie in keeping their forest in the family. And to those of involved in the process of making and using wood-based art supplies, it can mean promoting and supporting an industry dedicated to the preservation of our precious natural resource. We can all do our part to care for our national forests.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

50x130 is the Canvas Size Needed for this 40x120 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.

Tight'n'Up™ Liquid Canvas Retensioner

One of our most appreciated products helps make your canvas tighter! Stretching a canvas tightly can be a challenge. Our Frame Kits include the Corner and Brace Keys that you will need to add tension, but Tight'n'Up™ Liquid Canvas Re-Tensioner is a way that you can use to add tension to the canvas without needed to use the keys. It canvas be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets. Recommended for acrylic primed cotton or linen canvas. We do not recommend it for oil primed canvas because there are simply too many different types of oil primed canvas, but used conservatively at your own risk, it will tension any canvas.

A painter's language is the glimpse he offers into his soul. ♦ Robert Delaunay

Delving into the expansive art career of Robert Delaunay, one cannot help but be struck by the authenticity and depth of his work. This sentiment, echoing the belief that an artist communicates not just with colors or forms but with the very essence of their being, encapsulates Delaunay's philosophy. Each canvas he approached was not merely a surface to paint upon, but a window into his deepest reflections and emotions.

We too have that profound opportunity. Every piece we create is a conversation, a dialogue between our inner world and the external universe. It's not merely about the visual appeal, but the underlying message, the story, the heartbeat that pulses beneath the layers of paint. This dialogue becomes a bridge, connecting us with those who observe our work, inviting them to step into our world, to see through our eyes, and to feel the depth of our experiences.
