Application
Wool is used for numerous interior applications, such as upholstery, wallcovering, drapery, carpets, and rugs.
​
With wool carpet, it is important to consider location of application. However, natural wool carpet bounces back even after foot traffic and furniture placement.
​
-
Wool carpet is made from short, staple-length fibers and is durable and elastic
-
It comes in a variety of colors and patterns, and it can be recycled
-
Wool is also naturally flame resistant and helps with humidity by absorbing moisture
-
If sitting on the wool carpet, little strands of fiber can get on one's clothing. While harmless, this is something to consider.
-
For maintenance, blot and do not rub or the stain can spread. Use mild soap or undiluted vinegar. Apply lukewarm water and blot dry
