48x68 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True Dynamic Root-2 Proportion - 48x68 Size

This 48x68 is one of our Dynamic Root-2 Rectangle Root-2 Rectangle series.

The Dynamic Root-2 rectangle is an interesting proportion based on organizing your spatial composition with endless symmetrical divisions. The premise in Jay Hambridge's 1926 book is that the Dynamic Symmetry of individual elements are informed by their relationship to the entire composition. This very special proportion is guided by the square roots of integers and has a storied and historical basis in art.

_

It involves the use of geometric shapes and patterns in the proportion of the square root of 2 to 1 to create balance and harmony in a composition. This can be achieved by dividing a composition into a grid of squares or rectangles, and then placing elements within the grid in a way that follows the principles of dynamic symmetry. Dynamic symmetry is often used to create a sense of order and structure in a composition, and can be particularly useful for creating compositions that are harmonious and pleasing to the eye.

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.

• Produces a 3.5" deep stretched canvas (Actual depth is slightly thinner)
• 1.25" wide Stretcher Bar

No Finger Joints!

Solid Wood is far superior to finger jointed wood, which is many small pieces glued together, each with varying grain densities that absorb and shed moisture at varying rates, expanding and contracting non-uniformly as environmental conditions change, and causing the wood to bow and the finger joints to eventually fail.

A single homogeneous kiln-dried solid wood Stretcher Bar outperforms and outlasts a finger jointed Bar whose sole purpose is to save the manufacturer cost, not contribute to the archival value of artwork intended to last a millennium. As a manufacturer, Masterpiece® does its part to conserve as much wood as possible, and still provide a quality product that will out-perform any other in the marketplace.

Sustainability in our Forests and our Communities

At Masterpiece®, we believe in responsible and sustainable business practices. That's why we only use lumber from sustainably managed forests in our products. By doing so, we can help to protect our planet's forests, reduce our environmental impact, and support the communities that depend on these valuable resources.

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.

58x78 is the Canvas Size Needed for this 48x68 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 important thing is not to stop questioning. Curiosity has its own reason for existing. ♦ Albert Einstein

The brilliant physicist who redefined our understanding of the universe, Albert Einstein lived by these words. More than just a scientist, Einstein was a thinker who consistently challenged the status quo. He wasn't content with accepting things as they were but was driven by a relentless need to understand the underlying principles of the world. This unyielding curiosity, this unquenchable thirst for knowledge, was at the core of his groundbreaking discoveries.

Similarly, as artists, we share this innate curiosity. We constantly question, explore, and push boundaries. Where would our art be if we simply accepted the world as presented to us? Our role is to see beyond the surface, to interpret, reimagine, and present new perspectives. Every brushstroke, every color choice, and every composition stems from a series of questions and explorations. Just as Einstein saw the universe as a vast puzzle to be understood, we see the world as a canvas waiting to be transformed by our unique vision. So, let's never lose that spark, that childlike wonder. For in our endless questioning and curiosity, lies the essence of true creativity.
