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.

  • Produces a 3.5" deep stretched canvas (Actual depth is slightly thinner)
  • 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 Ponderosa Pine or Fir from the Pacific Northwest
 

Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

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 add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. 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.

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

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.

 

31x51 is the Canvas Size Needed for this 21x41 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.

We never really know what stupidity is until we have experimented on ourselves. ♦ Paul Gauguin

A pioneer in the world of post-impressionist art, Paul Gauguin was no stranger to taking risks and venturing into the unknown. His path from being a stockbroker in Paris to a painter in Tahiti was marked by a series of bold decisions, not all of which were met with immediate success or understanding. Yet, through his self-imposed trials and experiments, Gauguin forged an artistic identity that remains unparalleled in its originality and impact.

We too are confronted with moments of uncertainty and choices that might seem unwise to others. But it is through these daring endeavors that we truly learn, grow, and discover our unique voice. Gauguin's words serve as a candid reflection of this artistic path, reminding us that sometimes it's through our perceived missteps that we uncover the most profound insights and inspirations.


Celebrating the creativity in all of us, we've taken a step provide these words of wisdom and to immortalize Paul Gauguin through our own unique portrait. Pick up your brush and create!
