Originally I had it be a geometric plane but then I heard John Hodgman talking about crocheting a hyperbolic plane on his podcast. I had also read about this in the book Here’s looking at Euclid. Crazy how this was the first way a hyperbolic plane was expressed physically. Check out this website if you want to crochet your own: https://www.theiff.org/oexhibits/oe1e.html

(That’s where I got the picture.)
