Hyperbolic Plane, Negative Curvature 5:6
Mum bought me Crocheting Adventures with Hyperbolic Planes for my birthday. I have just finished chapter 1 (go me!!!)

The curvature of a surface is a measure of, well, how curvy it is. Most curved surfaces have positive curvature, turning them into spheres or ellipsoids and the like. If a surface has negative curvature you end up with, well, a frill, which is what I crocheted above by the cunning device of adding in an extra sixth stitch for every 5 on the row below (hence the ratio of 5:6).

I do need to get to grips with the terminology though. Luka asked if I could crochet her a hat and the online instructions I found were in gibberish.
