3D™ Pro 3.5 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.

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.

Sustainable Forests - A Precious Natural Resource
The air that we breathe depends upon our healthy forests the world over. For this reason, we only use lumber from the sustainable forests of the Pacific Northwest, so we can guarantee that our nation's precious natural timber resources are available for future generations.
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 strength—minimizing risks of cracks, splits, or bends—but 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.
28x31 is the Canvas Size Needed for this 18x21 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.

Critic asks: 'And what, sir, is the subject matter of that painting?' - 'The subject matter, my dear good fellow, is the light.
♦ Claude Monet
Claude Monet's profound connection to the nuances of natural light defined his career and set the tone for the entire Impressionist movement. Monet wasn't merely painting landscapes or gardens; he was capturing the ephemeral play of light upon them, showcasing how different hours and seasons transformed a single scene. It was revolutionary. Instead of historical events or grand portraits, he offered viewers an intimate experience of a fleeting moment.
Artists often find themselves trying to express the intangible, and like Monet, we understand that sometimes the beauty is not just in the subject itself, but in how it's perceived. We recognize the importance of perspective, of seeing the world in a new light – literally and metaphorically. While the canvas may present a scene, it's the light, the mood, and the atmosphere that bring it to life. It serves as a reminder for us to look deeper, to appreciate the nuances, and to remember that sometimes the magic is in the details that many overlook.
We've handpicked this empowering quote and offer insightful context to inspire your art. We've even created this unique portrait of Claude Monet to provide a personal touch to your browsing experience. Now start on your painting!
