A customer-customizable lamp includes a vertical support post mounted to a base plate. The customer selects from five different heights of decorative blocks to be mounted on the post. Each selected block may be provided in any one of five selectable colors or four selectable simulated wood grains. The selection of blocks and finishes are made on a web page with an interactive representation of the customizable lamp being displayed as the design is being created by the customer. The remaining height on the support post to be filled with decorative blocks is displayed. Once the post is filled and the customer has selected finishes for each selected block, the lamp design can be finalized for delivery to the customer. The customer selectable blocks and colors/finishes permit several million permutations so that the customer can create a highly individualized decorative lamp.
