Abstract
A process is disclosed for the making of a decorative carpet through the use of sublimable dyes. A shading effect is secured through the use of air flow control sheets that affect the flow of air through a transfer sheet and a carpet product adjacent thereto. By lessening air flow, the intensity of dye being transferred is also lessened so that shades of a certain color can be secured.
