Block printing has a long history originating in East Asia over 4,000 years ago. The earliest known example of block printing was done in China before 220 CE on silk cloth. The technique later spread throughout Asia and the world. The process involves carving designs and patterns onto wooden blocks which are then pressed onto fabric along with pigment dyes to create colorful prints. It is a labor intensive and time-consuming process requiring artistry and skill. Major centers of traditional block printing include India, China, Japan and communities still practice this centuries-old art today.
