The Espresso cup Räsymatto was designed by Sami Ruosalainen for Marimekko. The original porcelain range, without pattern design, goes by the name of Oiva and is used as a base for many other Marimekko designs. This particular design is called Räsymatto and was designd by Maija Louekari. The pattern was inspired by the classic rag rugs and their rows of slightly irregular sized knots.
