I didn’t include instructions on when to stop joining the top back to the top front for the neck opening.

When knitting the Top Front I suggest using a stitch marker to mark the start of the Front Neck shaping; this is the point where you want to stop joining the Top Back section to the Top Front section and then start joining again at the end of the Front Neck Shaping.

I have re-named this jumper Melissa’s Jumper
