Base Blocks took all bar 2g of the 1st hank of yarn
Body Blocks took almost a full hank of yarn each (all bar 3.5g each approx.)

I filled in the back using the oats colourway up to the reverse stocking stitch portion on the shoulders k2tog or p2 depending on the patterning each end of the row. I tried a variant that was in an email from Interweave knits but it was too big. I did a rib edging along the neck that was 6 rows long with a mitered centre. I also used the oats colourway for the sleeve and bottom edging.
