Abbreviated pi: a free lace knitting stitch pattern.

It’s Pi Day, at least when dates are considered from the US point of view: it’s 3/14 today. My husband is using this as an excuse to bake pie. I’m using it as an excuse to make another stitch pattern using the first five digits of pi: 3.1415.

I particularly like the unexpected way that if the knitting ends after row 2 or 8, there’s picots to be pinned out.

Happy Pi Day!

Notes:

  • 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.
  • Abbreviated Pi is a multiple of 118 stitches and 12 rows.
  • The cable crossings are optional, but I like it better with them.
  • I’ve made a stitch map for it.
  • 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.

Code process:

Here’s how I made this particular chart. I made a variety using all my layout methods, and this was the one I liked best.

encoding 31415 as a knitting stitch pattern

Triangles can make good tiles to repeat across a flat surface. I started at the bottom, counting squares from right to left, as if knitting.  Each digit of 31415 was counted separately. I counted 3 squares and then placed a marker; since there wasn’t a space on the first row, I put it in the first square of the second row; 1 square, then another marker; 4 squares, and so on. There are a bunch of blank squares left over, but they aren’t counted since another marker hasn’t been placed in that space.

Then I mirrored this triangle, and tiled it. I replaced the black squares with yarnovers and figured out where to place the decreases. As sometimes happens, the most obvious decrease locations looked best, making a motif that looks good in alternation.
