Abstract: A paper holder has an upwardly opening slot into which ribs project from each side of the slot. The ribs along the two sides are staggered and alternated with respect to each other so that a piece of paper inserted into the slot will assume a corrugated configuration and will accordingly remain upright in a free standing position. The base of the holder has a straight edge along which a measuring scale exists so that the holder may also be used for measuring and marking.
