I make stockings for all my nieces and nephews (I haven't knitted any yet, though - cross-stitch is my usual medium for these) and am always AMAZED at how big most designers make them. I have accidentally made some really huge stockings by choosing the medium-sized pattern. There's another nephew on the way and I think I'm making this one for him:
