Can anyone tell me how to HALF TURN to sew first piece inFortune Cookie Booties

Is that the pattern and is this the part you’re asking about?

Bind off leaving an 8” tail.
Turn cast on edge a half turn and sew to bind off edge
for right shoe. This is the top of the bootie. For
second bootie, turn cast edge half turn the opposite
way for left shoe. Weave in all ends.
