Muslin
Call it muslin, canvas, or cheesecloth, but cotton has been a constant companion to paper for many hundreds of years.
If you are looking for a source for canvas or muslin, especially for very large pieces, the best place to go is www.Rosebrand.com, where you will find a wide assortment of types and a fabulous catalog.
If you are looking for "paperhanger's canvas" a certain type of strong cotton underlayment in 36" widths, go to www.paper-hangings.com; this type is often specified for plank walls.
If you are looking for installation services for either type, go to Jim Yates at hiswallpaperspec@aol.com
