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.

Sustainability in our Forests and our Communities

At Masterpiece®, we believe in responsible and sustainable business practices. That's why we only use lumber from sustainably managed forests in our products. By doing so, we can help to protect our planet's forests, reduce our environmental impact, and support the communities that depend on these valuable resources.

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.

99x112 is the Canvas Size Needed for this 91x104 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.

Greatness lies not in being strong, but in the right using of strength. ♦ Henry Ward Beecher

Throughout his life, Beecher was witness to the Civil War, the fight against slavery, and the challenges of post-war America. He saw strength displayed in many forms, from the physical strength of soldiers to the moral strength of abolitionists. His observation about greatness speaks to the essence of using strength wisely, judiciously, and morally. For artists, this quote can be seen as a reflection on how they wield their skills and talents.

True artistic greatness isn't just about mastering a technique but about how one uses that technique to convey meaning, emotion, and perspective. Just as Beecher emphasized moral and just use of strength in socio-political contexts, he would likely advise artists to harness their artistic strengths in ways that resonate truthfully and profoundly with their audience.
