15x24 3D Pro Sausalito Canvas 3-1/2" #TS-1524

True Golden Mean Proportion - 15x24 Size

This 15x24 size is one of our Golden Mean sizes, considered the most pleasing shape to the eye!

The Golden Ratio, also known as the Golden Mean or Divine Proportion, is considered the most aesthetically pleasing proportion to the human eye. This proportion has been used in art and architecture for thousands of years, and countless examples can be found in nature, plant life, galaxies, and the human body. The Golden Mean can also be used as a guide to arrange your subjects on the canvas in concert with other Golden Mean shapes like an ellipse, star, triangle, and spiral, resulting in intriguing compositions. Many famous artists, such as Michelangelo, Da Vinci, Mondrian, Botticelli, Dali, and Seurat, have used this proportion in their art, and many contemporary artists continue to use it exclusively. The Golden Ratio can even produce some mathematically intriguing relationships that relate directly to art, architecture, science, and human intrigue. If you're looking for a challenge and inspiration, consider using a canvas in the proportion of the Golden Mean to create a composition that will come alive in the most intriguing ways!

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
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

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 add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. 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.

15x24 3.5" Deep Edge Heavy Frame Offers Maximum Support!

• Drawing depicts the exact frame construction, not the proportion
• 3.5" Deep Edge K3 Heavy Stretcher Bars are precision machined with a unique double tongue-and-groove corner joint that provides rock-solid torsional rigidity that resists warping or twisting, which is an important benefit for such a deep edge canvas
• One super strong 3/4" thick keyable brace provides maximum possible support for this 15x24 frame - Brace is permanently installed in the frame, but canvas tension may be increased by tapping-in the keys or wedges that slightly expand the size of the frame
• The Stretcher Bars have an proprietary utility groove on the inside perimeter of the frame which is used to attach braces and other optional frame supports
• The Masterpiece brace feature an exclusive system that allows you to increase the tension to the middle of the canvas, where the tension is needed the most; it's so unique it earned us a patent
• To increase canvas tension: 1) remove any staples in the corners and those that retain the brace keys in the middle, 2) tap all of the expansion keys further into their respective slots, 3) tighten and re-staple the canvas in the corners

Canvas Tension is in Your Control

In dry climates or air conditioned environments, the lack of moisture in the air causes wood frames to shrink and the canvas fibers to narrow and elongate making the canvas more slack and resulting in a loss of canvas tension. In some instances, the canvas could have waves on the surface resulting in an unsightly viewing experience.

Our 3D™ Pro 3.5 professional frames provide the functionality for you to slightly expand the size of the frame in the corners and the middle of the canvas, thereby increasing canvas tension all across the surface. The difference between a loose canvas and a tight canvas is just 1/8" of an inch, so a small adjustment using our corner and brace keys makes an important difference in canvas tension.

• Helps to prevent waves that occur in a loose canvas
• Increase canvas tension by tapping-in the corner and brace keys
• True professional class canvases make it possible for you to adjust the canvas tension

Cross Braces Make it Tighter

A tightly stretched canvas on an un-braced frame overpowers the Stretcher Bars causing them to bow inward and thereby lose tension. Sometimes that bow can expose a space in picture frames.

When a canvas is stretched on a properly supported frame, the cross-braces prevent the Bars from bowing thereby achieving maximum canvas tension. To increase the canvas tension even more, simply tap the corner and brace keys further in their slots. Properly supported frames provide you with the control over the canvas tension of your canvas and painting.

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.

It is well with me only when I have a chisel in my hand. ♦ Michelangelo

The meditative act of chiseling was more than a profession for Michelangelo; it was a lifeline, an intimate dance between him and his medium. In those moments, he felt aligned, purposeful, and truly alive. Every artist has that one tool, technique, or process that resonates deeply, providing not only comfort but a profound sense of belonging. For many of us, it's when our hands are stained with paint and our brush feathers the canvas surface, fingers tap dancing on the piano keys, or when the pen meets the paper, that the world feels right. It's in these moments that we not only create but actually find our true selves.

Tight'n'Up™ Liquid Canvas Retensioner

While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can 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.
