15x21 Monet Pro Raw No 8 Canvas 1-1/2" Deep #MRE-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.

Explore other sizes in this same 7:5 aspect ratio:

5x7 • 10x14 • 20x28 • 25x35 • 30x42 • 35x49 • 40x56 • 45x63 • 50x70 • 55x77 • 60x84

Monet™ Pro 1.5" Deep 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 1.5" deep stretched canvas canvas (Actual depth is slightly thinner)
• 1-5/8" wide Stretcher Bar
• Frames with a dimension of 20" 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

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.

15x21 Monet Pro Keyable Braced Frame

• Drawing depicts the exact frame construction, not the proportion
• Precision machined heavy duty keyable tongue-and-groove Stretcher Bars
• A 3/4" 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

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 Monet™ 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

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 Environment Promotes a Sustainable Economy

The use of lumber from sustainably managed forests is not only environmentally responsible, it also helps to support the economy and preserve jobs in the forestry industry. By choosing products made with sustainably sourced lumber, consumers can help to ensure that these industries remain strong and sustainable for years to come.

The only foes that threaten America are the enemies at home, and these are ignorance, superstition, and incompetence. ♦ Elbert Hubbard

A progressive thinker and influential writer of the late 19th and early 20th centuries, Elbert Hubbard was known for his pointed critiques of society. He observed the cultural landscape with a discerning eye and was unafraid to spotlight its shortcomings. His observation about America's internal threats feels timeless, underscoring challenges that societies face across epochs.

Hubbard's words ring with a particular resonance. Throughout history, we've been tasked with holding mirrors up to society, reflecting both its beauty and its flaws. In facing the enemies of ignorance, superstition, and incompetence, we find rich sources of inspiration. Our art becomes a powerful medium, not just for showcasing creativity, but also for igniting conversations, challenging norms, and seeking truths. Whether it's a canvas depicting social inequalities or a sculpture that challenges traditional beliefs, our creations embody a resistance to these internal foes.

Hubbard's insight serves as a reminder of the role we play in the broader cultural narrative. As we interpret and convey the world around us, we contribute to the collective effort of combating the forces that threaten progress. The act of creation is, at its core, a form of resistance and a call for understanding, growth, and enlightenment.
