My definition of the saying 'snug as a bug in a rug': me in bed under a duvet and quilt with books and hot-water bottle.
Now I'll be even snugger with John Betjeman et al as I've just knitted a hot-water bottle cover from a couple of skeins of cashmere yarn bought from here quite a few years ago. I never got round to using it, but always thought how good it would feel under my feet (almost as good as in my hands - it's amazing how sensitive feet are). So in an idle-I-can't-sit-and-watch-TV-with-nothing-to-do moment, I cast on 45 stitches on 4.5mm needles and knitted with double thickness yarn, making it up as I went along. I ran out of yarn to make a 100% cashmere back, so used a single strand plus a strand of Rowan wool/cotton yarn. I deliberately made sure the knitting was abnormally thick and tight in order to achieve maximum tactile pleasure and bottle insulation. It really is remarkably soft and warm, and makes being a bug even more enjoyable.
I may be some time abed.
