Happy Tau Day!

Just for the fun of it, I’m going to post occasional stitch patterns in honor of geeky days on the calendar.

So what is Tau Day? Tau is a constant twice as big as pi, and it is apparently more useful than the number pi. Here is the Tau Manifesto for your mathematical pleasure. The main thing for my purposes is that 6/28 is a date that approximates Tau.

Therefore, I have encoded 628 as charts for lace knitting, knitted cables, and a grid for use in any craft that can use a grid as instructions. (This is not, of course, all of Tau; it just seemed like a useful stopping point.

I’ve written this lace pattern to be lace every row (though it’s on the easier end – none of the decreases are worked directly over any of the yarnovers). Alternating plain rows could be added easily – go for it!

Abbreviation key:

  • 1/1 LC: Slip next stitch to cable needle and place at front of work, knit 1, then knit 1 from cable needle. (Purl these stitches on wrong side rows)
  • 1/1 RC: Slip next stitch to cable needle and place at back of work, knit 1, then knit 1 from cable needle. (Purl these stitches on wrong side rows)
  • k: knit.
  • k2tog: knit 2 stitches together as if they were 1. (Right-leaning decrease)
  • p: purl.
  • ssk: slip each of the next 2 stitches as if to knit, then knit them together through the back loop. (Left-leaning decrease)
  • yo: yarn over.

This stitch pattern is a repeat of 8 stitches and 10 rows (if converted to work in the round, it’s a repeat of 5 rows)

Row 1 (RS): k1, yo, k1, k2tog, ssk, k1, yo, k1. [8 sts]
Row 2 (WS): p2, 1/1 LC, 1/1 RC, p2.
Row 3: k1, k2tog, yo, k2, yo, ssk, k1.
Row 4: ssk, yo, p4, yo, p2tog.
Row 5: knit.
Row 6: p1, yo, p1, ssp, p2tog, p1, yo, p1.
Row 7: k2, 1/1 RC, 1/1 LC, k2.
Row 8: p1, ssp, yo, p2, yo, p2tog, p1.
Row 9: k2tog, yo, k4, yo, ssk.
Row 10: purl.
