True Dynamic Root-5 Proportion - 8x18 Size
This 8x18 is one of our Dynamic Root-5 Rectangle Root-5 Rectangle series.
The Dynamic Root-5 rectangle is an inspiring proportion based on organizing your spatial composition with endless symmetrical divisions. The premise in Jay Hambridge's 1926 book is that the Dynamic Symmetry of individual elements are informed by their relationship to the entire composition. This very special proportion is guided by the square roots of integers and has a storied and historical basis in art.
It involves the use of geometric shapes and patterns in the proportion of the square root of 5 to 1 to create balance and harmony in a composition. This can be achieved by dividing a composition into a grid of squares or rectangles, and then placing elements within the grid in a way that follows the principles of dynamic symmetry. Dynamic symmetry is often used to create a sense of order and structure in a composition, and can be particularly useful for creating compositions that are harmonious and pleasing to the eye.

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.
- Produces a 2.5" 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

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.

MuseumWrap™ Stretching Technique
With more than a half a century of American engineering, Masterpiece® designs and builds its own proprietary stretching equipment that enables us to produce the finest and most tightly-stretched canvas on the market.
- Drum-tight stretch!
- Up to 50% tighter than other methods
- Balanced tension across the surface
- Uncut folded corners make it possible to remove and re-stretch canvas on the same size frame
- Usually the corner folds are on the long sides

The canvas you choose is the foundation for your painting, but also serves as symbol of the quality that you as an artist stand for, and reflect on your own brand. Masterpiece® serves as your silent partner to create your next masterpiece. You "wow" them from the front, while we "wow" them from behind.

There's a universe inside every stroke, and a story behind every hue.
♦ Paul Gauguin
Paul Gauguin's life was as colorful and multifaceted as the palettes he used in his art. From his early beginnings in France to his transformative years in Tahiti, every experience, emotion, and interaction played a pivotal role in shaping his distinctive artistic language. It was this accumulation of life experiences, interspersed with bouts of introspection and personal discoveries, that breathed life into his canvases.
When Gauguin speaks of the universe within a stroke and the tales tied to hues, he's emphasizing the depth and complexity within art. For artists, the canvas isn't just a piece of fabric; it's a portal into our psyche, our past, and our passions. Every choice, from the stroke's direction to the shade of blue or crimson, narrates a chapter of our lives or echoes a sentiment we wish to convey. As we immerse ourselves in our craft, the choices we make are reflections of our internal landscapes. Just as Gauguin's works encapsulated his struggles, aspirations, and the cultures he embraced, our creations are the chronicles of our soul, waiting to be deciphered by those who dare to look closely.
Draw inspiration from the words of wisdom by Paul Gauguin, plus our interpretation of its meaning, along with our own rendered portrait of Paul Gauguin. Now get busy on your own canvas!

Tight'n'Up™ Liquid Canvas Retensioner
While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can 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.
