Organized in the 1950s as the Venetian Blind Council, the Window Covering Manufacturers Association (WCMA) represents the interests of the window covering industry manufacturers, fabricators and assemblers. Industry products include blinds, shades, shutters, curtains, curtain rods, drapes, drapery hardware, and other window treatments. WCMA has three membership categories: Manufacturers, Fabricators and Associates. Membership in the Manufacturers category is limited to companies engaged in the business of manufacturing or assembling interior or exterior window covering products. The Fabricator category includes members whose companies are engaged in the business of fabricating or assembly of interior or exterior window coverings. The Associates category includes members whose companies are not eligible for membership in the Manufacturer or Fabricator categories, but are interested in the welfare of the window covering industry. Suppliers of goods and services to manufacturers and fabricators comprise many of the members in the Associates category.
