Laughter may the best medicine, and this fabric collection is designed to cheer up the youngest, and often most vulnerable, patients. To combat the boredom and stress of treatments, Funnybone from CF Stinson is a conversation starter with five patterns. For example, Knock Knock, a 100%-recycled solution-dyed nylon, features jokes woven into each stripe, while I Spy, made of 71% post-consumer recycled polyester and 29% nylon, allows users to find objects, such as pearls and tiaras, hidden in its weave.
