18x18 3D Pro Grenoble Canvas 3-1/2" #DG-1818

True 1:1 Square Proportion - 18x18 Size

The 18x18 square size is a little less common but gaining in popularity.

The square is perhaps the most intriguing proportion, as it is root of all of the other proportions. It is commonly used in both photography and art. Squares are typically used as the center canvas of a triptych or as a single canvas hung at a 45° angle. The square proportion is long used with medium format professional cameras, and most photographs we see on websites and social media are based on square images. Since all sides of the canvas are the same length, your eye is drawn evenly across the surface of the painting creating a sense of harmony, balance, and a generally a pleasing visual experience. The square format is also a good choice for artists who focus on geometric shapes or patterns in their work, as the regularity of the square shape can help reinforce these elements. Some artists enjoy the challenge of working within the confines of a square format, as it forces them to think creatively resulting in intriguing compositions.

3D™ Pro 2.5 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.

• 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

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.

• Drawing depicts the exact frame construction, not the proportion
• 2.5" Deep Edge K2 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
• No Brace Required for this size
• To increase canvas tension, remove any staples in the corners and tap all of the expansion keys further into their respective slots, then tension and re-staple the canvas in the corners

Sustainably Managed Forests

We use lumber grown in the sustainable forests of the Oregon, Washington, and California, where there’s more standing timber today than last century! Our forests purify the air, provide oxygen, and reduce global warming. More trees are needed on this planet, not fewer. Therefore, we use lumber grown in responsibly managed forests, so future generations can benefit from our collective responsible actions today.

Specially Dried and Heat Treated Lumber

Our wood is handpicked from a curated group of environmentally responsible lumber mills in the Pacific Northwest. By adhering to our precise drying and heat-treatment standards, these mills produce lumber with nearly half the moisture you'd find in common home improvement outlets or lumber yards. This meticulous process not only enhances the wood's strength—minimizing risks of cracks, splits, or bends—but also elevates its dimensional stability. Such quality, despite its premium, is paramount in creating professional canvases designed to uphold the sanctity of your cherished art throughout the years.

I escape to the primitive to avoid the conventional baseness of today's art. ♦ Paul Gauguin

In Paul Gauguin's pursuit of genuine artistic expression, he found himself increasingly disenchanted with the mainstream, perhaps even superficial, trends of his time. The contemporary art scene was fraught with imitations and redundancies, lacking the authenticity Gauguin craved. Such a sentiment is shared by many artists who, at times, feel hemmed in by the expectations of their era or the demands of a particular audience.

The term primitive, as Gauguin used it, shouldn't be mistaken for unsophisticated or simplistic. Instead, it encapsulates a raw, unfiltered form of expression, free from the constraints and pretenses of modern civilization. For artists, such unspoiled realms offer a fresh canvas, unburdened by preconceived notions or societal judgments. It's a realm where we can explore and experiment without fear, giving voice to our innermost passions and desires.

Turning to the primitive is more than just a stylistic choice; it's a profound statement on the nature of art itself. By seeking solace in the rudimentary, Gauguin and those of us inspired by his ethos are making a deliberate choice to prioritize genuine emotion over technique, authenticity over approval. In doing so, we are reminded that true artistry often lies in the ability to shed the extraneous, to distill our visions to their purest essence, and to bravely share that vision with the world, undiluted by the demands of convention.
