Product Description It's a little curious, this life-sized organ made entirely of felt. But hey, Felted Curiosities is what we do!This listing is for one HUMAN-SCALE brain SIZE: Approximately 6-7" The brain is a fleshy pink wool with 3-dimensional wrinkles created by sculpting wool fiber with a felting needle. The core of the brain is yarn. Other felted organs are available: spleen, gallbladder, appendix, brain, lungs, uterus, tonsils, stomach, intenstines, etc. I've been honored to have my handmade organs featured in an award winning ad campaign (Gyro Denver - 2013).
