Pieni Unikko apron cotton-linen from Finnish brand Marimekko is a beautiful apron made from a pleasant blend of cotton and linen. The apron is decorated with the popular Unikko pattern designed by Maija Isola in 1964. Despite Marimekko's founder Armi Ratia announcing a ban on floral patterns at the time, Maija Isola was able to persuade her to adopt the poppy flower design.
