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.

• 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

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.

What is Sustainable Forestry?

To a forester, the term "sustainable" could mean exercising industry adopted forestry practices to maintain a forest indefinitely. To a logger, the process of proper care for the trees remaining after a harvest. To a landowner, their interest may lie in keeping their forest in the family. And to those of involved in the process of making and using wood-based art supplies, it can mean promoting and supporting an industry dedicated to the preservation of our precious natural resource. We can all do our part to care for our national forests.

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.

100x110 is the Canvas Size Needed for this 90x100 Frame

Please note that you will need a canvas that is at least 10 Inches larger than the actual frame size to ensure proper stretching. This will provide ample material to stretch the canvas and attach it to the back of the frame. If you prefer to attach the canvas from the edge of the stretcher frame, you can reduce the size of your canvas by approximately 3/4" all the way around the frame. This will allow you to paint on the edge of the canvas and hang your artwork without needing a separate picture frame. And, if you ever need to remove the canvas from the frame and re-attach it, you'll have enough material to do that too.

It is not enough to know your craft – you have to have feeling. Science is all very well, but for us imagination is worth far more. ♦ Henri de Toulouse-Lautrec

A mastermind of the Post-Impressionist era, Henri de Toulouse-Lautrec lived a life characterized by passionate expression and the pursuit of genuine emotion. In the bustling Montmartre district of Paris, he distinguished himself not just by his innovative techniques, but by the depth of emotion he conveyed. This sentiment captured in the quote underlines a belief many of us share: while technical skill is invaluable, the soul of art lies in its emotional resonance.

Throughout his career, Henri recognized that raw talent wasn't enough. Tapping into our own vulnerabilities and experiences elevates our artistic work, giving it depth and meaning. In an age where science and technology continually advance, it's a gentle reminder that while knowledge is crucial, imagination is the compass that guides our artistic path. We're reminded to prioritize the heart over mere technique, embracing the boundless landscapes of our imagination.
