48x84 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True Palindromic Proportion - 48x84 Size

This interesting palindromic 48x84 size is not based on any specific proportion, but this one is based on the 7:4 ratio.

The Palindromic Series of canvas sizes challenges artists to explore the potential of symmetrical shapes in their work. This series is characterized by sizes that read the same forwards and backwards, such as 12x21 and 34x43. Unlike other canvas sizes, there is no actual proportion that defines these shapes, thereby creating a sense of wonder and a challenge for artists to push the boundaries of their compositions. In fact, the very symmetry of the palindromic shape can add an extra layer of intrigue and mystery to the composition, prompting viewers to question the artist's intentions and the underlying meaning of the piece.

While the use of palindromic shapes in art is not new, it continues to be a source of fascination and inspiration for many contemporary artists. These shapes can be used in a variety of ways, depending on the artist's style and vision. Some artists use palindromic shapes as a focal point, while others incorporate them into the background or use them as a pattern on the canvas. The use of palindromes can also serve as a nod to linguistic and literary elements, as they are often used in wordplay and puzzles. This reference can add a layer of meaning to the artwork, making it more engaging for viewers who appreciate the subtleties of language and symbolism.

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 Ensure More Wood for Communities

Using lumber from sustainably managed forests is not only the responsible thing to do, it's also a way to ensure that the wood products we rely on continue to be available in the future. By supporting sustainable forestry practices, we can help to ensure a steady supply of wood products while also protecting the environment and supporting local communities.

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.

58x94 is the Canvas Size Needed for this 48x84 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.

The function of muscle is to pull and not to push, except in the case of the genitals and the tongue. ♦ Leonardo da Vinci

Beyond his iconic art, Leonardo da Vinci was a keen observer of the human anatomy. His countless sketches of the human body testify to his relentless curiosity about how we are constructed and how we function. In a time when detailed study of the body was limited, da Vinci's observations were revolutionary, offering insights that bridged art and science.

This particular observation, focusing on the muscular system, showcases his characteristic wit and precision. While it might first appear as a simple anatomical fact, there's a deeper wisdom embedded. In art, as in life, there are forces that pull us, that shape our actions and creations. Recognizing these forces, understanding them, and harnessing them, are crucial to the creative process. Similarly, just as the tongue and the genitals have unique roles in human expression and procreation, there are elements in our artistic practice that deviate from the norm, that push boundaries, and help us articulate our most profound ideas and feelings. Embracing these nuances, we can better navigate our path as creators and communicators.
