The Random Knitting Continues Unabated

Look! I made a yarn cozy! Seeing as though it's about minus a million degrees here today, I couldn't in all good conscience let my poor cotton yarn freeze it's little fibers off. It's summer weight, it can't cope with New York winters.

Ok, so I haven't completely lost the plot (although the drugs they gave me yesterday to knock me out for an endoscopy have me thinking otherwise). This isn't really a yarn cozy but more of a toe cozy. Still not getting it? Well my sister is having her foot broken and realigned today (get well soon, sis!) and she's going to have her foot in a cast for six weeks. While it's not quite so arctic in Manchester as it it currently is here, I can't have her freezing her little toes off so I made what is essentially a giant sock-toe.
The yarn is Debbie Bliss Merino DK (seen in another incarnation here) in a heinous Barbie pink. I cast on 60 stitches on 3.5mm needles, did about an inch of k2 p1 ribbing, switched to plain stockinette and fudged a few deceases in on a spiral until I figured it'd probably fit. I mean, how big is a cast, how much toe will actually be exposed? I have no clue so I hope this will be stretchy enough to cover all that needs covering. If not it'll make a great prosthetic boob which is why I knitted the little i-cord nipple on the top, not for easy taking off or anything. I'm going to knit a second one slightly differently just in case this doesn't stretch enough at the cast on. The next one will have a wider opening and a bunch of eyelets so that a silly, twiddly ribbon can be threaded through to pull it tight. That one will be purple and probably wont have a nipple because, really, no one wants to look at a purple boob.
