18x18 3D Pro Vintage L21C Canvas 3-1/2" #TO-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 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.

• 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.

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.

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.

Through pure painting, we can find the pure emotion. ♦ Robert Delaunay

When Robert Delaunay posited his belief about painting, he was diving into the very soul of the act of painting. A champion of abstraction, he understood that true art transcends mere representation. For him, the canvas was not a passive receptor of colors and forms but a conduit for raw, unfiltered emotion.

Artists, when engrossed in their work, engage in a delicate dance with their materials. Through this act, we channel our innermost feelings, desires, and fears. The purity of our intent and emotion bleeds into the strokes, colors, and forms. When we immerse ourselves in pure painting, devoid of preconceptions and guided by intuition, the result is a piece that not only showcases our technical prowess but also mirrors our soul. For both the creator and the observer, this creates a shared moment of revelation, where pure emotion stands unguarded, inviting understanding and empathy.
