Hi!
I'm currently on lesson 19 (preparing front back and sleeves) and have stumbled upon an error in the prepping of the CB.



When the hiplines and chestlines WERE brought to alignment, I was left with this bulge. When the bulge was straightened out, the panel sat diagonally, overlapping the vent line.
My actions to troubleshoot so far:
I reprinted and carefully reassembled the paper pattern. This turned out to be in the same proportion as the one originally made, so this was ruled out as being my issue. I carefully redid Lesson 9 (drafting and cutting traditional jacket). The results turned out the same.
I feel stumped, what could I be doing wrong?
Thank you in advance
