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 Fights Against Climate-Change

Sustainable forestry practices are an important tool in the fight against climate change. By using lumber from sustainably managed forests in our products, we can help to reduce the carbon footprint of our business and support the health of the planet. It's a win-win for everyone involved.

20x28 is the Canvas Size Needed for this 12x20 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.

No part of life is so small and insignificant that it does not offer space for artistic aspirations. ♦ Gustav Klimt

Gustav Klimt, renowned for his sensuous and opulent paintings, stood at the forefront of the Symbolist movement. His works, replete with intricate patterns and ethereal figures, celebrate the beauty inherent in every facet of existence. Klimt's deep appreciation for life's intricacies, both grand and minute, informs this quote, and is evident in the meticulous detailing that characterizes his art.

Life is a vast canvas, offering infinite opportunities for creative exploration. The smallest moments, the seemingly inconsequential happenings, can be the genesis of profound artistic expression. Artists often find themselves captivated by the mundane, seeing potential where others see the ordinary. We, as creators, are reminded to look beyond the obvious, to seek inspiration in the overlooked and the undervalued. Klimt's perspective challenges us to harness the boundless possibilities that life presents, and to continually seek beauty and meaning, regardless of the scale.

The spirit of artistry is inspiration and creation. We too are inspired by the wisdom of this quote and hope you are inspired by our interpretation thereof, as well as this inimitable portrait we created of Gustav Klimt. Go create!
