Removing marking lines from fabric has sometimes been a cause of concern especially when trying to get rid of the lines without hurting the fabric. Not anymore! With the Sewline Aqua Eraser your worries are erased along with the marking lines. It works rather like a fountain pen with a reservoir you simply fill with water or a water and detergent mix. Your finger pressure on the soft grip dampens the special soft fiber point. By lightly dabbing or running this point along the line or mark the special point absorbs the pencil or water-based ink mark. So much quicker and easier than fiddling with a sponge or cloth. When the point of the Aqua Eraser becomes discolored simply pull it out and slip in a new point.
