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.

Sustainably Managed Forests
We use lumber grown in the sustainable forests of the Oregon, Washington, and California, where thereÕs 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 strengthÑminimizing risks of cracks, splits, or bendsÑbut 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.

44x121 is the Canvas Size Needed for this 36x113 Frame
Please note that you will need a canvas that is at least 8 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.
Tight'n'Up™ Liquid Canvas Retensioner
One of our most appreciated products helps make your canvas tighter! Stretching a canvas tightly can be a challenge. Our Frame Kits include the Corner and Brace Keys that you will need to add tension, but Tight'n'Up™ Liquid Canvas Re-Tensioner is a way that you can use to add tension to the canvas without needed to use the keys. It canvas be sprayed on the back of a canvas to repair most canvas tension issues.
With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets. Recommended for acrylic primed cotton or linen canvas. We do not recommend it for oil primed canvas because there are simply too many different types of oil primed canvas, but used conservatively at your own risk, it will tension any canvas.

An artist painting a picture should have at his side a man with a club to hit him over the head when the picture is finished.
♦ John Singer Sargent
John Singer Sargent's striking statement here is both humorous and profound. Throughout his career, he was known for his meticulous attention to detail and his endless pursuit of perfection. Yet, he also recognized the dangers of overworking a piece. Many of us know this struggle all too wellÑthe challenge of knowing when to lay down the brush and declare a piece complete. The balance between refinement and spontaneity, perfection and authenticity, is a tightrope we all walk. The presence of this figurative man with a club is a reminder to us that sometimes, the magic of art lies in its imperfections, in the rawness of a moment captured rather than its polished facade.
Reflecting on Sargent's vast body of work, it becomes clear how he grappled with this balance in his own creations. From the luminous skin tones of his portraits to the dappled light of his landscape works, there's a sense of life, movement, and reality. For us, his words serve as a cautionary tale. As artists, it's essential to stay connected to our initial vision, to trust our instincts, and to recognize when our work, in its beautiful imperfection, speaks more loudly than any further stroke could. Sometimes, it's about knowing when to step back and let our art breathe on its own.
We've handpicked this empowering quote and offer insightful context to inspire your art. We've even created this unique portrait of John Singer Sargent to provide a personal touch to your browsing experience. Now start on your painting!
