A compact, highly-portable hook and sling suspension assembly for rolled sheet materials (including partially or substantially unrolled sheet materials) such as background paper rolls commonly used in photography. The assembly includes a suspension cable with a pair of generally C-shaped hooks at its opposite ends. Each hook has an upper shank portion, a vertical back portion, and a horizontal insert portion. A linear relationship between the merger point of the back and insert portions, the hook's point of attachment to the cable, and the cable's central suspension point, results in a self-adjusting assembly which is highly effective in suspending a roll of sheet material and in permitting that material to be unrolled (and re-rolled) without damaging the ends of the roll or the side edges of the sheet material.
