Chicago Saxony Carpet
The number one selling carpeting in Chicago is a twisted saxony carpet. This is a cut pile carpet with the yarn tips sticking straight up but pointing in different directions. This creates a two toned look that helps to hide foot prints and vacuum lines. It has been heralded as trackless carpet, I would put the emphasis on "less" as it will still show some tracking and vacuum marks.
Saxony carpet is not to be confused with a shaved velvet cut pile which is very formal look. The yarns are shaved several times to give a smooth solid rich color appearance. A velvet will show every foot print and vacuum mark. If you need further information on this in Chicago carpet, contact Mathew Klujian and Sons.
