Space-Filling Terrazzo – Getting Started

Space-Filling Terrazzo – Getting Started 640 480 mathgrrl

This is the first in a series of posts about a space-filling riff on Tinna’s Terrazzo Afghan. Our design is going to start off looking like one of Tinna’s Terazzo squares, but it’s going to continue as a larger and larger square, with lots of different but “space-filling” patterns along the way. It won’t be ONE space-filling curve (sorry, math geeks), but it will fill space efficiently as we build the pattern out from the center.

I haven’t been stress-printing before the election, YOU have. Well, maybe you will after this post, at least.

Fitted Face Mask for People Who Aren’t Great at Sewing

Fitted Face Mask for People Who Aren’t Great at Sewing 2560 1920 mathgrrl

Over the past weeks I’ve iterated mask designs many times, acquired a bunch of sewing supplies, and learned from a lot of online patterns and videos. This mask design has a sewn-in nose wire, elastic loops that go all the way around your head, a filter sewn inside the mask, and minimal exposed seams. It’s washable and reversible, so you can decide which side is the outside after you’re done sewing it, or each time you wash it.

Okay. Deep breath. It’s time to start figuring out how to teach online… I mean, how to do Actually Do It Well, not just as an emergency solution thrown together over a frenzied and sleepless week.
