You never know what you’ll learn at the library!<\/p>\n

Recently, the Corvallis-Benton County Public Library began hosting a monthly Fiber Arts Meetup, which is culminating next weekend (Nov. 18) with a Coral Reef Community Art Collaboration<\/a>. Although there are many kinds of relevant crafts and projects, one that was featured was hyperbolic crochet<\/a>. Rather than being an exaggerated form of crochet, this is the process of creating “negatively curved” surfaces. This is a word for a surface that curves in two directions away from what is “flat” (tangent), like a saddle (bending down on your left and right, and up in the front and back). A positively curved surface bends only in one direction, like when you’re on top of a mountain looking down on all sides. A surface with zero curvature would be infinitely flat in all directions.<\/p>\n

You can play with this in crochet. If you crochet a doily or a potholder, that generally would have zero curvature. But if you wedge in extra stitches so that they simply cannot lie flat, you’re going to generate a curved surface. The method I learned for hyperbolic crochet simply has you doubling the number of stitches in each hole as you go around, an exponential growth that creates a very organic-looking ruffled structure:<\/p>\n

And because yarn (and knitting) is flexible, the same shape can shift into another 3D configuration where the negative curvature is even more evident:<\/p>\n

It is surprisingly fun to play with this object and feel how it moves and shifts. What you can’t do is make it lie flat, at least in our three-dimensional world. Each row has twice as much length within it as the previous one. Such a fascinating construction! Thank you, Mari Beth, for teaching me!<\/p>\n","protected":false},"excerpt":{"rendered":"
