A Moment in the Shade of Plum Trees. In late summer, the plum trees of the north bear sweet and juicy fruit. While we wait for it, the fruit can be enjoyed immortalized in interior and table setting textiles. The Luumu (Plum) pattern is perfect for those moments when it's time to make yourself at home. With Luumu, you can add warmth to the kitchen, living room, or bedroom. Designer: Lasse Kovanen.
