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.

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
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.

87x94 is the Canvas Size Needed for this 79x86 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.

My painting carries with it the message of pain.
♦ Frida Kahlo
Frida Kahlo's life was a vivid tableau of adversity, resilience, and raw emotion. Physical pain, due to her tragic accident, and emotional turbulence, arising from her tumultuous personal relationships, constantly shadowed her. Yet, instead of letting these challenges overcome her spirit, Kahlo channelled them into her art, making each canvas a testament to her trials. For artists, we find a kindred spirit in Kahlo. We see that art can be a vessel to contain our sufferings, translating our deepest sorrows into visual stories that resonate with others.
Such honest portrayals, laden with genuine emotion, are what make artworks immortal. As Kahlo laid bare her pain on the canvas, we are reminded of the transformative power of artistry. Through creation, we not only immortalize our experiences but find catharsis, offering both ourselves and our audience a means to navigate the labyrinth of human emotions and find solace.
Echoing the timeless spirit of artistry, we bring you this quote paired with our beautiful portrait of Frida Kahlo that we created. Let your colors on the canvas speak!
