Im working on clue 3 making size 2 and have knitted rows 1- 12 ready to split for sleeves. But my yoke length is just under 20 cm instead of the suggested 17.5. But I think my tension is okay - I've added up all the rows in the clues so far and given the gauge then my length is right. Looking at zanete's tutorial, I can see that Zanete has knitted rows 1- 12 before splitting for sleeves. So, should I undo rows to get length of 17.5cm before split or carry on with length of 19.5cm? Will it matter so much?
