I made this scarf using the directions for crocheting a double hyperbolic plane found in the downloadable pamphlet on this website
http://crochetcoralreef.org/makeyourown/index.php. I did it to gear up for creating a satellite coral reef here in Salt Lake City. http://lakebonnevillecoralreefproject.blogspot.com/

Basically I just made a very long chain, then turned and worked 1 in 2nd ch from hook, 2 sc in next ch and repeated that to the end. Then instead of turning, I worked maybe 3 or so sc in the end ch and then continued in pattern up the other side. I just kept repeating this, going round and round until I went through 2 skeins of yarn. I’m really quite happy with it:)
