Inspired by the credited pattern but I didn’t exactly follow the pattern.
Cast on 88 stitched and did a bit more than one inch of 2X2 ribbing then added two stitches. Four rows of stocking stitch then used a graph taken from Google images knit over 12 stitches with 3 stitches in between for a total of five repeats. A couple more rows of stocking stitch then decreased at a rate of 8 sts on alternate rows.
Turned out to be the right size for a 6 year old boy.
