18x108 3D Professional 2.5" Deep K2 Stretcher Frame Kit

True 6:1 Super Extreme Proportion - 18x108 Size

This stunning 18x108 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.

3D™ Pro 2.5 Stretcher Bar • 1/2" Canvas Clearance

1/2" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretcher Bar.

• 1.25" wide Stretcher Bar
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach

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.

Forests need People, and People Need Forests

Using lumber from sustainably managed forests is a way to support the health and well-being of our planet and its inhabitants. By choosing products made with sustainably sourced lumber, we can help to protect the environment, support local communities, and ensure a sustainable future for generations to come.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

26x116 is the Canvas Size Needed for this 18x108 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.

Painting is a way of capturing the beauty that remains. ♦ Pierre-Auguste Renoir

Pierre-Auguste Renoir, an iconic figure of the Impressionist movement, dedicated his life to immortalizing fleeting moments and the sublime allure of everyday life. The vibrant scenes of joyous gatherings, playful light, and delicate beauty found in his work give testament to a deeply held philosophy: the power of art to seize and preserve the timeless essence of beauty. While landscapes may change, and moments fade into the annals of time, art offers us a refuge, a space where beauty is forever captured and cherished.

Every brushstroke is more than just pigment on a canvas; it is an intimate dance with time, an effort to hold onto something precious. We, as creators, often find ourselves inspired by the ephemeral, driven to encapsulate the transient beauty before it slips away. In doing so, we not only offer the world a visual feast but also a reminder to appreciate the beauty that surrounds us. Renoir's insight compels us to embrace our unique ability to ensure that even in the face of change, the beauty we witness remains eternal in our work.
