Solid Wood is Archival - Finger Jointed Wood is Not
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 make are part of the archival process.
The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.
As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.
Our Ecosystem Depends on Healthy Forests
Forests play a vital role in our planet's ecosystem. They absorb carbon dioxide, filter air and water, and provide habitat for countless species of plants and animals. By using sustainably sourced lumber, we can help to protect these important ecosystems and ensure that they continue to provide these valuable services for generations to come.
22x31 is the Canvas Size Needed for this 12x21 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.

Art should be a part of life. It doesn't need to be expensive to be enjoyed.
♦ Mary Cassatt
Within the simplicity of Mary Cassatt's assertion lies an underlying challenge to traditional notions of art's accessibility and worth. Art, in its vast array of forms, is more than a luxury or an exclusive possession for the elite. It's a universal language, a conduit for human emotions, experiences, and narratives.
For Cassatt, the democratization of art was evident in her own career. She defied conventions of her time, focusing on the everyday beauty of domestic life, often showcasing the intimate moments between mothers and children. It is these universal themes that remind us, artists, that the most profound subjects are often found in our daily lives. It encourages us to appreciate and document the nuances that make up our shared human experience. The value of art, as Cassatt suggests, is not always in its price tag, but in its capacity to touch and inspire us, resonating with the cadence of our own lived experiences.
Creativity is a dance between inspiration and innovation. Our own self portrait creation of Mary Cassatt twirls alongside these profound words, hoping to set the stage for your next artistic performance. Now go do your dance on the canvas!
