91x104 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 8:7 Near Square Proportion - 91x104 Size

The 8:7 aspect ratio has a subtle horizontal emphasis, providing a slight stretch that offers more width than height. This creates a composition that feels expansive without losing its compactness. The ratio works well for scenes that need a bit of extra breathing room horizontally, such as landscapes, wide portraits, or still life arrangements.

The near-square format adds a sense of balance, while the slight horizontal lean invites the viewer's eye to move side to side, offering gentle movement across the canvas. It’s an ideal choice when looking to create compositions that feel open yet grounded, with enough space to explore without overwhelming the viewer with too much width.

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.

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.

Sustainably Managed Forests Coexist with Mankind

We use lumber grown in the sustainable forests of the Pacific Northwest, where there’s more standing timber today than last century! There will always be a demand for wood pulp and fiber, but striking a harmonious balance with human coexistence is the essential strategy to which we subscribe. Sustainably managed forests increase our health and abundance of our forests which can be in harmony with this precious natural resource.

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.

101x114 is the Canvas Size Needed for this 91x104 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.

With deep family ties and a legacy spanning since 1965 in California, Masterpiece® has been the epitome of unmatched quality in Stretcher Bars across North America. Our commitment to pioneering excellence has crowned us as the forerunners in the world of professional fine-art canvases.

I get madder and madder on giving back what I feel. ♦ Claude Monet

Claude Monet, the celebrated French Impressionist painter, left an indelible mark on the art world with his revolutionary approach to capturing the essence of a moment. Born in 1840, Monet's life was marked by a relentless pursuit of truth in his art. His quote reflects the frustration and passion that often consumed him in his quest to convey the vivid emotions and sensations he experienced. As artists, we can relate to this burning desire to translate our innermost feelings into our work, a process that can sometimes evoke intense emotions. Monet's dedication to expressing what he felt is a testament to the profound connection artists have with their creations, and it reminds us that our art is a conduit for our deepest emotions and experiences.

Monet's life was filled with challenges, including financial struggles and the loss of loved ones, but his determination to capture the fleeting beauty of nature through his impressions gave rise to a new era in art. His relentless pursuit of truth, even as he battled personal and artistic challenges, serves as a beacon of inspiration for us as artists. It reminds us that our passion and dedication to our craft can drive us to persevere, innovate, and create works that resonate with the world. We share in Monet's frustration and determination, knowing that our art is a reflection of our souls, and we must persist in giving back what we feel, just as he did.
