Lion Brand® Fun Fur® - Lion® Suede - Vanna's Choice® - Homespun® GAUGE: Exact gauge is not essential to this project. NOTES: Hyperbolic Crochet is the name given to applying a mathematical principle to crochet patterns. A hyperbolic plane expands exponentially from any point on its surface, always curving away from itself. You can easily crochet a hyperbolic surface by increasing at a constant rate throughout the piece. Hyperbolic growth in nature gives rise to the ruffled shapes of coral, kelp, and sea anemone. Crocheting coral forms is a great opportunity to try different yarns and stitches, and is just one example of the types of project that hyperbolic motifs may inspire you to do. The Institute for Figuring created the concept of the Coral Reef with hyperbolic crochet and have been developing this concept since 2005.

Any basic crochet stitch - single, half double, double, or triple - can be used in the patterns. Feel free to alternate stitches within a pattern - to change yarns as it strikes your fancy. Try using different hook sizes to achieve different looks. Work with a single strand of yarn or a combination of yarns worked together with a large hook. RU
