The CFI Installation Resource Manual, Chapter 7 explains the characteristics of patterns, installation problems with patterns, locating the match, pattern tolerances and guidelines that are helpful for the installation community. The Patterned Carpet Resource Guide and the accompanying video are available from CFI.
