So, how many people get totally frustrated from the ssk or the s1, k1, PSSO coming out all crooked when your k2tog lies perfectly flat and beautiful? Me? Me? I get so, SO angry about that.
Well, I figured out a trick to have the exact, same straight line for your left-leaning decreases. I know! (!!!!!)
Here's the trick. On the ssk, instead of slipping both stitches knit-wise, slip the first knit-wise and the second purl-wise. Then knit them together through the back legs. Tada! Your left-leaning decreases will sit perfectly straight, no more jogging, no more crookedness.
Check it out in this close-up.
Yeah, those lines are S(kw)S(pw)K(tbl)!
