Elite™ Professional 1.5" Deep B2 Bar • 1/2" Canvas Clearance

A Canvas Clearance of 1/2" 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.

No Finger Joints!

Solid Wood is far superior to finger jointed wood, which is many small pieces glued together, each with varying grain densities that absorb and shed moisture at varying rates, expanding and contracting non-uniformly as environmental conditions change, and causing the wood to bow and the finger joints to eventually fail.

A single homogeneous kiln-dried solid wood Stretcher Bar outperforms and outlasts a finger jointed Bar whose sole purpose is to save the manufacturer cost, not contribute to the archival value of artwork intended to last a millennium. 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.

Biodiversity in our Forests is the Key to Life as we know it

By using lumber from sustainably managed forests in our products, we can ensure that the forests will continue to thrive and provide valuable resources for years to come. Sustainable forestry practices help to maintain the health and biodiversity of the forest, which benefits not only the environment, but also the local communities and businesses that rely on the forest for their livelihoods.

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 strengthÑminimizing risks of cracks, splits, or bendsÑbut 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.

27x34 is the Canvas Size Needed for this 21x28 Frame

Please note that you will need a canvas that is at least 6 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.

The model is always right. ♦ Henri de Toulouse-Lautrec

A master of Post-Impressionist painting, Henri de Toulouse-Lautrec frequented the spirited cabarets and theaters of Montmartre. His artworks captured the essence of the characters he portrayed, from celebrated singers to everyday people. When he says, The model is always right, he was expressing a deep respect for authenticity and the raw, unfiltered truth that models brought to his canvas.

This sentiment serves as a poignant reminder. It's easy to get caught up in our own interpretations or stylistic preferences, but true artistry often lies in capturing the authenticity of our subjects. Just as Lautrec celebrated the unique idiosyncrasies of his models, we too should embrace the beauty in the unrefined and the genuine. Whether it's the curve of a cheekbone, the arch of an eyebrow, or the story in someone's eyes, the model brings a truth that we are entrusted to convey on the canvas. In doing so, we not only honor our subjects but also bring greater depth and dimension to our work.
