Best of Three: Tree Shower Curtains Yesterday we looked at some tree-inspired designs and today's Best of Three is a roundup of tree-themed shower curtains... This Brown Tree Shower Curtain from Urban Outfitters is $40. (This design appears to be a knockoff of Marimekko's Tuuli shower curtain.) Marimekko's Kaiku Shower Curtain is $48 from Anthropologie. Unison's Larch Shower Curtain is exclusive to CB2 and is on sale for $30.
