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 thereÕs 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.

23x39 is the Canvas Size Needed for this 15x31 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.

Forms and rhythms in painting are more and more dominated by geometry, by calculation. ♦ Robert Delaunay

Robert Delaunay, a titan of Orphic Cubism, was no stranger to the transformative power of geometric shapes and calculated rhythms in art. For Delaunay, the world of art was a vivid tapestry where mathematics met imagination. He recognized that beneath the sweeping strokes and vibrant hues lay a meticulous framework, often rooted in geometry and precise calculation.

For many artists, the idea of combining rigid mathematical constructs with the fluidity of artistic expression might seem counterintuitive. But in reality, these seemingly opposite worlds can coexist harmoniously. When we weave geometry into our art, we tap into the universe's inherent order and symmetry, which can enhance the depth and perspective of our creations. The calculated rhythm, born out of precise geometric patterns, can evoke feelings of balance and harmony in the viewer's psyche.

Embracing this insight, we can see the potential to innovate and redefine the boundaries of our craft. When we find the balance between intuition and calculation, our art becomes a beautiful dance of emotion and structure, passion, and precision. It's a reminder that in the vast landscape of artistic expression, there's a place where the heart's impulses and the mind's calculations intersect, leading to masterpieces that are both emotionally resonant and geometrically profound.
