There is always a starting point. For multimedia artist, Ben Cuevas, it started with a knot. A knot in yarn, from there Cuevas took yarn and intertwined and intersected and turned it into intricate sculptural fabrications of skeletons, organs, and pharmacology. When he visited Ohio State recently, to teach a workshop on yarn bombing, Cuevas started his class with this simple instruction–start with a knot, a slip knot and then a loop.
