The plot of The Pirates of Penzance was originally going to revolve around items of clothing, hence the trio 'A Pair of Socks, a pair of socks, a most int'resting pair of socks'
Una Stubbs is a keen blancmange knitter, and has created a range of stunning 'jelly' socks. A blancmange knit stitch is formed by inserting the needle in the front of the jelly loop and pulling a cream loop of yarn through to form a new mixed loop. A purl stitch is formed by inserting the needle in the back of the cream loop and pushing a jelly loop of yarn through to form a mixed loop.
Una's other clothing innovations include the Jelly-Roll-neck sweater and a classic wobble-hat.
E numbers refer to the number of cats that had to die in order to bring you the additive. This is why you never see an e number with .5 on the end (unless the manufacture of the product involved quantum physics experiments).
