When Australian-born Margaret and Christine Wertheim created The Coral Reef Project in 2005, they not only helped to bring awareness to the devastating effects of climate change on the Great Barrier Reef, they started a movement that spoke to thousands of crocheters.

Margaret is a science writer and artist who, with her artist twin sister Christine, realized that crocheted hyperbolic planes look like coral reefs. This similarity between yarn craft and natural element was first published in 1993 by Dr. Daina Taimina, now-retired Cornell University mathematician and knitter/crocheter, who realized that this type of math, manifested frequently in nature, can be reproduced using yarn to crochet the beautiful curves and contours. Dr. Taimina’s TedxTalk demonstrates the math in understandable terms. The crochet approach is fairly simple: It involves crocheting in the round and doubling the number of stitches in every round so that the piece ruffles dramatically.
