Abstract: A valance board assembly has a channel member of a stiff, hard, material such as, for example, a compressed laminate. The channel member is formed on an open-ended channel and contains a board of a lightweight material susceptible to receiving and holding pins affixed therein, and which is coextensive with, and substantially completely fills, the channel member. At least two plastic bracket members are configured to hold the channel member resting thereon, and stop members prevent it from sliding off. Decorative fabric may be affixed by pins to the lightweight material and draped to provide a decorative window effect.
