The sign makes a circle in the air, then pokes the thread through the needle. The tips of the right index finger and thumb make contact with the tips of the left index finger and thumb. The left hand uses the same handshape as the right hand.
Do this sign initialized with "P" hands and it will mean "perfect." The tips of the middle fingers touch.
