89x89 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 1:1 Square Proportion - 89x89 Size

Large and glorious, this bold 89x89 odd size square makes a commanding statement.

The square is perhaps the most intriguing proportion, as it is root of all of the other proportions. It is commonly used in both photography and art. Squares are typically used as the center canvas of a triptych or as a single canvas hung at a 45° angle. The square proportion is long used with medium format professional cameras, and most photographs we see on websites and social media are based on square images. Since all sides of the canvas are the same length, your eye is drawn evenly across the surface of the painting creating a sense of harmony, balance, and a generally a pleasing visual experience. The square format is also a good choice for artists who focus on geometric shapes or patterns in their work, as the regularity of the square shape can help reinforce these elements. Some artists enjoy the challenge of working within the confines of a square format, as it forces them to think creatively resulting in intriguing compositions.

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.

Tree Replanting - Essential to Sustainably Managed Forests

Harvesting timber provides humans with an essential natural resource, but replanting trees at a rate higher than a harvest is a key component in humanity's effort to guarantee a healthy forest for the future. Increasing our number of trees is just as essential to our economy, as the harvest itself, which is why we select only timber harvested from responsibly managed forests.

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.

99x99 is the Canvas Size Needed for this 89x89 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.

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.

I find happiness when the sun paints shadows on the earth. ♦ Paul Gauguin

Paul Gauguin's life was characterized by his constant search for beauty, not just in the celebrated or obvious, but in the subtle interplay of light and shadow, the everyday and the overlooked. His time in places like Tahiti was not merely a quest for vibrant colors but also for the contrasting shadows, the unseen narratives, and the silent whispers of nature.

In our art careers, it is easy to get caught up chasing the dazzling, the spectacular, or the popular. But Gauguin's sentiment reminds us that sometimes, true happiness and artistic fulfillment can be found in the quieter moments, the interplay of light and dark, and the stories that shadows tell. We are often drawn to the luminosity of success and recognition, but there's a profound beauty in the spaces in between, waiting for us to discover and cherish.
