Letters and bicycle helmets

I'm slightly potty about fonts!  It's sort of snuck up on me but I realise that so much of what appeals to me is about lettering.  All the lovely disparate lettering on these old ice cream tubs next to the good old classic penguin books.  Heavenly.
Anyway, on another note I'm really keen to get back onto an even keel.  The children are a bit like wild animals and they're constantly HUNGRY.  Yesterday we bought new cycle helmets for Rufus and Ottilie and they insist on wearing them round the house which makes the place seem just a tiny bit more insane.
