15x21 Vincent Pro Tahoe Canvas 7/8 Inch Deep #VT-1521

True 7:5 Photography Proportion - 15x21 Size

Another widely used proportion in photography is the 7:5 aspect ratio, but is relatively uncommon in art, save for the 5x7 size. It is commonly accepted as a pleasing proportion. Some artists choose this proportion to add visual interest by breaking away from more traditional shaped canvas sizes. There are only a handful of standard canvas sizes in this ratio, but there are a whole collection of (what we call) Lost Sizes in this aspect ratio, which are often unknown sizes that add intrigue to the final composition.

5x7 • 10x14 • 20x28 • 25x35 • 30x42 • 35x49

Vegan Ground:

There are no animal products that make-up the sizing and the primer for this fine canvas. Historically, traditional canvas grounds have included egg tempura, pigments with cow urine, and of course, rabbit skin glue. In today's rapidly advancing world, there are many more choices available for artists who prefer non-animal based products that perform far better than their animal-based predecessors.

15x21 Vincent Pro Keyable Braced Frame

• Drawing depicts the exact frame construction, not the proportion
• Precision machined medium duty keyable tongue-and-groove Stretcher Bars
• A 1/2" thick keyable brace (1.5" wide) provides sturdy support for this 15x21 size frame - Brace may be removed in reinserted at any time
• An exclusive slot is milled on the inside perimeter of the 21 Stretcher Bars to which the Brace and the expansion wedges attach
• Patented keyable brace allows the frame to be tensioned in the middle of the canvas, where the tension needed the most
• 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

Vincent™ Pro 7/8" Deep Bar • 5/16" Canvas Clearance

5/16" 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 Stretched Canvas Frame.

• Stretcher Bar Profile produces a 7/8" deep stretched canvas
• 1.5" wide Stretcher Bar
• Frames with a dimension of 16" and up have a groove machined in the center inside perimeter to which cross braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

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.

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.

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.

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 Vincent™ Pro 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

MuseumWrap™ Stretching Technique

With more than a half a century of American engineering, Masterpiece® designs and builds its own proprietary stretching equipment that enables us to produce the finest and most tightly-stretched canvas on the market.

• Drum-tight stretch!
• Up to 50% tighter than other methods
• Balanced tension across the surface
• Uncut folded corners make it possible to remove and re-stretch canvas on the same size frame
• Usually the corner folds are on the long sides

Since 1965, our passion for perfection has driven us at Masterpiece® to construct professional quality canvases that artists around the nation desire. Your art is better and more valuable when the materials you use are complementary to the blood, sweat, and passion you will paint on top.

I love Brittany; here I find the savage, primitive quality. ♦ Paul Gauguin

Brittany, a region in Northwestern France, held a special place in Paul Gauguin's heart. While many associate him with the tropical allure of Tahiti, it was in Brittany where he first began to deeply explore the idea of primitivism in art. For Gauguin, Brittany represented an escape from the urban sophistication of Paris, a place where he could immerse himself in a rawer, more elemental landscape.

But what is it about the savage, primitive quality that drew Gauguin, and why does it call to so many of us in our artistic pursuits? Perhaps, it is the authenticity and unfiltered expression it embodies. In a world increasingly dictated by conventions, the allure of the primitive reminds us of the purest essence of artistry. As artists, we often strive to capture that unrefined essence, seeking to tap into something deeper and more genuine than the veneer of civilization allows. By embracing the primitive, we acknowledge the power of raw emotion, untempered by societal expectations, and allow it to guide our creations.

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.
