Raw #8 Cotton 18 oz Unprimed

Super heavy weight unprimed canvas. Take control of your art, prepare your own ground, or use bare canvas expanses as part of the art. Great for staining or pouring, resulting in a fluid and spontaneous convergence of the image and fabric.

• 100% Cotton 18 oz. per square yard
• Super Heavy Weight, Dense Weave, Robust Texture

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.

• Produces a 2.5" 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

Solid Wood is Archival - Finger Jointed Wood is Not

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 make are part of the archival process.

The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.

As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.

13x21 2.5" Deep Edge Heavy Frame Offers Maximum Support!

• 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

Biodiversity in our Forests is the Key to Life as we know it

By using lumber from sustainably managed forests in our products, we can ensure that the forests will continue to thrive and provide valuable resources for years to come. Sustainable forestry practices help to maintain the health and biodiversity of the forest, which benefits not only the environment, but also the local communities and businesses that rely on the forest for their livelihoods.

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

One of the most celebrated features about 3D™ Pro 2.5 canvases is the patently robust framing system that makes it possible to increase the tension in the middle of the canvas, where the tension is needed the most. Our well-made keyable bracing system supports the canvas indefinitely. Braces prevent the stretcher bar frame from bowing-in so the canvas stays tighter long-term.

I am the primitive of the method I have invented. ♦ Paul Cézanne

Often hailed as the bridge between 19th-century Impressionism and 20th-century Cubism, Paul Cézanne was no stranger to forging new pathways in the realm of art. His assertion about being the primitive of his own method encapsulates his groundbreaking approach. In an age dominated by artistic conventions, Cézanne dared to think differently, breaking away from traditional techniques to create something distinctively his own.

We can find inspiration in Cézanne's words and journey. While the path of innovation can be isolating, it is also deeply rewarding. Embracing our unique perspectives and experimenting with unfamiliar methods can lead to the birth of fresh, transformative ideas. By courageously stepping into uncharted territories, we too have the potential to become the trailblazers of the techniques we bring to life. Cézanne's legacy serves as a testament to the power of originality and the wonders it can unveil.
