30g w/w acrylic yarn
J hook for starting chain, I hook for main stitching

Would be better with a different color “snake” for a few rows in the middle

Added body length

Seamed with green yarn (RP color), hardly visible because cast-on and bind-off (both in FP color) stitches are so prominent. Maybe a different seaming/joining technique?

Stitch counts:
W = 12, B = 4

Sections with B and W should have been B+2, W+2 to allow for corners

W top back & sleeve backs
2 cuff
2 sleeve front
B front
2 half hem
B back vertical
W midback band
