15x90 3D Professional 2.5" Deep K2 Stretcher Frame Kit

True 6:1 Super Extreme Proportion - 15x90 Size

This stunning 15x90 size part of our Super Extreme 6:1 Aspect Ratio series.

This dramatic extreme proportion is used in both art and cinematography to bring focus on a sliver of your overall subject. This proportion can have a sense of depth and perspective in the painting, particularly for landscapes or compositions with a strong sense of spatial relationships. The canvas could be used for a wide, expansive landscape with a distant horizon line, or to create a sense of depth in a still life or portrait. The long and narrow shape could be used to create a sense of stability or symmetry, with elements arranged in a way that is visually balanced. Or you might use it to create tension or dynamism in the composition by placing elements in unexpected or asymmetrical positions. Using this proportion will no doubt make you think creatively about how to use this unusual shape to your advantage. This can be somewhat challenging, but it may help the artist to develop a new technique and approach to a composition in this format.

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.

Selective Harvesting in our Sustainable Forests

Intelligent selective harvesting of timber is an ecological method to replace the natural occurrences of forest fires and disease and landslides that can devastate forests. This is all part of the process of sustainable forest management to which we subscribe when we choose which lumber we use in our products.

23x98 is the Canvas Size Needed for this 15x90 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.

Art is not freedom from discipline, but disciplined freedom. ♦ John F. Kennedy

John F. Kennedy, the 35th president of the United States, was not just a political figure but also an avid supporter of the arts and culture. His administration bore witness to a renaissance in American arts, and his words often echoed the intrinsic values that art and culture brought to society. Kennedy's leadership was characterized by vision and pragmatism, and his perspective on art mirrors this duality.

For many, art represents a realm of unbridled expression, but Kennedy reminds us of an essential truth: true artistry emerges from the harmonious blend of freedom and discipline. The art world might seem a playground of infinite possibilities, but it's within certain boundaries that artists find the space to innovate. By understanding the techniques, tools, and traditions of their medium, artists gain the expertise to push boundaries and redefine norms. In this way, it is the discipline that elevates our craft, allowing us to explore and express with clarity and impact.
