Using some cotton blend yarn from my stash, I recently cast-on the Baby Roots Cardigan. Knitting it in a unisex color (maize), I'll add boyish or girly buttons once we find out what it needs to be.
It has been a bit of a challenge thus far though as there has been some errata in the pattern. I contacted the designer and she's been helping me figure out some of the errors in stitch numbers but I'm working on figure out some of the others on my own. (x+y)*6+2-1... Man, I should have paid more attention in math as a kid.
Actually, with a few tweeks, I'm moving along nicely enough on this sweater. We'll see how it turns out and how much my math skills help or hurt the process.
