• A Unique System

    The Otto System is a unique, frustration-free artist's tool that allows paper of all weights to be securely stretched in preparation for watercolor use. The unique clamp design of the tool eliminates damage to the deckle edge from tacks, staples or tape commonly caused by other stretching techniques and products on the market. The finished painting is as flat as the original sheet with no resulting paper damage or clamp impressions.
