KH-260 Field Notes 1: Trash Swatch

KH-260 Field Notes 1: Trash Swatch 2016 1512 mathgrrl

This is the first of a series of blog posts that will catalog our adventures with a Brother KH-260 knitting machine. We’ve set up the machine and know the basics of using it in various ways, but what now? In this “Field Notes” series we’ll share quick notes about what we learn as we go forward. Nothing fancy, just a day-to-day journal of what works and what doesn’t. Like everything we post here at Hacktastic, we’ll talk a lot about our failures and problems, since that is where learn the most!

Crochet Rainbow Blanket

Crochet Rainbow Blanket 2560 1920 mathgrrl

This very simple blanket pattern is great for using up yarn scraps (or to give you an excuse to purchase more yarn, let’s be honest). The pattern is very forgiving about yarn thickness, and gives you a chance to play with color transitions. The finished piece is comfy and casual. The holes are fun to push your fingers through, and make the blanket airy and cool. Based on the Vintage Vertical Stripe Crocheted Blanket Pattern from Bella Dia, except with two rows of each color and some attention to detail at the edges.

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.

Electoral State Stackers

Electoral State Stackers 2016 1512 mathgrrl

I haven’t been stress-printing before the election, YOU have. Well, maybe you will after this post, at least. Fire up your 3D printer(s) because there are dozens of things you need to print before Tuesday, including each of the 50 states (and DC, which has 3 electoral votes), sized to each have approximately the same area, with heights determined by number of electoral votes.
