Getting those drafting lines from fabric has sometimes been a cause of concern when we wanted to get rid of the lines without hurting our fabric. No more with the new Sewline Aqua Eraser! It works something like a fountain pen with a reservoir that you fill with water or a water and detergent mix. Your finger pressure on the soft grip then 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!
