The backing yarns—warps, stuffer, filler, wefts—may be jute, wool, cotton, or treated paper or a combination of two or three of these materials. They are usually of a quality commensurate with the surface material.
See that the selvage is strong and the binding carefully sewed on or, in the case of Lokweave, that there is sufficient sealer around the edges to lock the tufts securely.
Handmade floorcoverings are by and large more expensive than those made by machine. A cheap handmade rug is just as foolish an investment as a cheap one made by machine.
Here, though the labor costs are considerably higher because of the greater number of hand-tied knots in a fine fabric, the import duties and shipping and handling charges are so great a part of the cost that no one should buy a handmade rug unless it is well woven with sufficient material of good quality.
