A cup holder is disclosed in the form of a sheet with distal ends. A web is formed in one of the ends, and a corresponding slot is formed in the other end such that the ends interlock. Thus the cup holder is assembled by rolling the sheet and interlocking the ends. The sheet can be an elongate band of pressed material, preferably pressed paper pulp, and is preferably formed with multiple nubbins and depressions. In one embodiment, the sheet has a top and bottom that are arcuate and concentric, and matching webs and cuts are formed in each end of the sheet, with the cuts being perpendicular to the top of the sheet.
