Not yet a sock - more like a tube

I'm having great fun with this sock - the yarn pattern makes it interesting - I've always been a sucker for variegated yarn, knitting furiosly to see how the colour pattern evolves - this Opal yarn has teh same effect - I can't stop knitting for wanting to see the next colour. I spent an hour or so on the sock yesterday and here, I present 'my first tube' I don't feel ready to attempt a heel flap tonight , so that is it for today!. I handed over the blue cardigan today - for my colleague's grandson, much to her surprise and I have a feeling of great achievement and a desire never to knit that pattern ever again.
