Swim: a mosaic knitting chart

Last week, I encoded the word swim and made it into a lace stitch pattern and a needlework chart. For this week’s post, I reworked a code grid I made while planning that post and turned it into a mosaic knitting stitch pattern. (I used the process described in this post.)

A nice thing about mosaic knitting is that the charts are similar to the final appearance of the knitting, so I’m not going to provide a swatch. Mosaic knitting looks difficult, but it’s not as hard as it looks! Basically, knit two-row stripes, and slip stitches from the row below to make the contrasting pattern.

Here’s a detailed blog post I wrote about how it works.

This is a Barbara-Walker-style mosaic chart. Each row of squares in it represents two rows of knitting (which is why there’s a row number at each end). The square in the column to the right of the row numbers indicates the color of yarn being worked in that line. So in rows 1 & 2, all black squares are knit or purled, and all white squares are slipped with the yarn being held on the wrong side of the work. In rows 3 & 4, all white squares are knit or purled and all black squares are slipped.


  • This is a stitch pattern such as might be found in a stitch dictionary. This is not a pattern for a finished object.
  • Swim is a multiple of 8 stitches and either 24 or 24 + 12 rows.
  • The non-slipped stitches in the second row of each stripe may be either knit or purled, as desired.
  • Designers, please feel free to use this in your patterns. I’d like credit but won’t be offended if people don’t give it.
