After the Two-Colour Balloon Knit Stitch in my last post, this post showcases the Three-Colour Balloon Knit Stitch.
It's essentially the same knit stitch with the addition of a third colour on rows 11 to 16. The stitch motif requires a multiple of 8 plus 4 stitches and is worked over a total of 16 rows. All stitches are slipped as if to purl.
