Yes kiddies, that's what happens when you swatch with one yarn and then switch to another for the final project. That's the difference between 9 rows per inch and 7 rows per inch. Turns out that those 2 rows per inch add up rather dramatically, and if only I'd left some eye holes it would be a nifty G.H. themed ski-mask.
Ragnar...swatch twice, silly pirate.
