Well, I just couldn't help myself.
After making the pompom for the top of the stripey tea cosy, I had to make another one. And another. And somehow I ended up with a large pile of pompoms, just before my cousin's birthday.
Now, I'm not entirely sure that a thirteen year old Dr Who obsessive has much use for a pompom scarf, but it also works quite well as a draught excluder, or just a cheery hanging-on-the-wall decoration, or stuffing for a cushion...
And it did get the pompom making bug out of my system, for the time being at least.
