How to knit Checker Stitch:
Work with a multiple of 12 stitches + 1 + 2 edge stitches.
Cast on 27 stitches (12 + 12 + 1 + 2 edge stitches) and work according to chart.
The chart shows only Right Side Rows.
On Wrong Side Rows, work sts as they appear and purl any yarn-over loops.
The patt rep = 12 stitches wide.
Begin with 1 edge stitch, work patt rep throughout, end with 1 stitch after patt rep and 1 edge stitch.
