Chiyogami is a style of paper originating in traditional handmade washi, that's decorated with colorful designs taken from nature. It's still made by traditional methods in workshops, some dating back to the 19th century. Over 1,000 patterns are in use, applied either by brush or by woodblock printing. Used in origami, this paper is now becoming popular overseas too. In Japan, it's also widely used as a craft paper for making stationary items and ornaments.
