When the woolly-pulley came out, I was at Coningsby. What was very amusing was the alacrity with which the first of our aircrew stitched his wings on ( it was not officially sanctioned initially IIRC) .
One of our more mature (ex-Valiant and Canberra Recce) winged brethren quietly inquired of the said individual if he had remembered to also stitch them on his pyjamas.
