How to sew a Hyperbolic Blanket (2021)

At first I misread this as "hypergolic" and had concerns. The actual thing is much nicer, and the description of how to get the curved seams right was helpful. This is something I've never quite figured out but I'd like to get a lot better at it.

To be fair, a hypergolic blanket would still keep you warm. Potentially for the rest of your life!
