Many symmetries are found in folk art; we have already seen some from Celtic knotwork designs.

Allow me to share some Lithuanian designs. Most of these patterns are woven into cloth or sashes. Many exhibit some symmetries, some exhibit many symmetries, others exhibit almost none, despite looking "symmetric" at first glance.
