Oh heck, I've been knitting lots of these while watching all the great drama on TV recently, but sadly I'm no expert - I have about 80 beginner hats in a bag ready to drop off at Age UK, and I've got a feeling some of them might fail the quality control. I'm a dab hand at the dropped stitch 
I actually felt very proud when I managed my first stripey bobble hat! But I like a challenge too, and will have a go at something a bit more advanced.
One thing though, GNHQ. Don't they all have to be handed in before Christmas?
