How the clue works
The definition is needlework — literally working with needles, which is exactly what this practice involves. For the wordplay, you've got a giving you A, then prize giving you CUP, and finally point in time when Juliet left — that's JUNCTURE with the J (Juliet in the NATO alphabet) removed, leaving UNCTURE. String them all together and there's your answer.
