In everyday life, knot has many practical uses that are usually overlooked such as shoelacing. In  sports  and  activities  like  sailing  and  rock  climbing,  a  knot  can  mean life or death. Knot now plays an important role in modern surgery too. A logical extension to the digital world is to model these objects in virtual space. We present an interactive system for designing knots that combines sketch-based interface and physical simulation together.
