# 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.

### Notes:

• 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!
• This is a stitch pattern such as might be found in a stitch dictionary. It is not a pattern for a finished object. You will need to add selvedges or some other form of knitted stitches to either side.
• Tau lace is a multiple of 8 stitches and 10 rows. (If converted to work in the round, it’s a repeat of 5 rows)
• Designers, please feel free to use this stitch in your patterns. I’d like credit but won’t be offended if people don’t give it.
• If you like my posts like this, please consider supporting me on Patreon or donating with my Paypal tip jar in the sidebar. Thanks!
