When working in an art-related business, sooner or later a request will come up as to whether or not you are able to stretch a canvas. Some simply use strainer bars to accomplish this task, however, strainers are not considered acceptable for stretching fine art because of their inability to expand. A more professional and functional instrument to use (especially when dealing with larger sized paintings) would be stretcher bars with keyed-out corners (and keyed-out sides if including cross bars). Keyed-out stretcher sets have been used for centuries, and for those who truly understand the characteristics and properties of how canvas behaves, it is clear that ordering these types of bar sets are, without a doubt, the only way to go. Let’s talk for a brief moment about canvas, while considering temperature and moisture changes in the air. Canvas is constantly moving as a result of increases and decreases in temperature, as well as humidity and dryness fluctuations – increased humidity alters the canvas by loosening the tension and the canvas becomes slack. Keyed-out stretchers allow one to adjust and stretch the framework, ultimately helping to keep the canvas looking top-notch and taut. Keep in mind there are certain factors to consider regarding stretching canvas and using stretcher keys, as well as when and how to make necessary adjustments. Needless to say, education on proper use and guidelines for alterations are advised to ensure each individual canvas is being handled properly. Foster is very passionate about quality and tradition, so it is very natural how we came to craft and offer these types of stretchers to the public, along with our stock and specialized moulding.
