Oya is a lace technique which uses a tiny straight needle to make even tinier loops and knots and as the knots are tightened the stitches also grow smaller. At first glance, oya appears very similar to crochet lace. However, it is much finer, designed to be sewn onto something else and differs in its ability to be two-dimensional or three-dimensional. There are two main stitches – the square and the triangle. Phases in the work are called root oya, rock oya and main oya.
