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.

23x49 is the Canvas Size Needed for this 13x39 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.

Sculpture is the art of the hole and the lump. ♦ Auguste Rodin

Auguste Rodin, the mastermind behind iconic works like The Thinker and The Gates of Hell, possessed an uncanny ability to breathe life into stone and bronze. With a chisel and hammer in hand, he transformed blocks of raw material into forms bursting with emotion and vitality. His quote serves as a deceptively simple yet profound insight into the nature of sculpture and, by extension, the creative process itself.

The lump represents the raw material, the substance, the palpable reality. But it's the hole, the space, the void, that lends context and meaning. Just as silence in music can be as potent as a crescendo, the spaces and gaps in sculpture are integral to its overall narrative. They shape the light, cast shadows, and create dynamics, giving a three-dimensional voice to the artist's intent. Similarly, as we approach the canvas, we juggle both substance and absence, crafting narratives with what's both there and what's purposefully left out.

So, as we stare at a block of clay or a blank canvas, remember that it's the delicate dance between the solid and the void, the said and the unsaid, that adds meaning to the composition. It's not just about what we put into our art, but also about what we choose to leave out.
