Marimekko Cushion Cover Kuisma. The Kuisma pattern cushion cover is made of linen. The cover has a concealed zipper on one side and a picot edge finish. The Kuisma (St. John´s wort) design shows the last flowers of fall swaying in the wind. The leaves are already tired and curled, and the most delicate of the flowers disperse in the air. By painting the flowers with watercolors on wet paper, Aino-Maija Metsola created a beautiful misty atmosphere in the pattern.
