The best way to deal with a stressful situation and painful waiting is to start a new, engrossing project. I give you the beginning of a sleeve for Inishmore:
I have a bunch of Cestari wool that I bought at last year's Maryland Sheep & Wool and I've been looking for a good project. Something cabled, earthy, traditional and with a gauge I could achieve in this yarn. Bonus points of the garment is designed by Alice Starmore. The cables are working out well, it's very easy to read them and see what to do next, and I've done more than half a sleeve in less than two days. The yarn is rough and rustic and I absolutely love it.
Incidentally, the stressful event ended up being so much less difficult than I was expecting. The dentist was able to save my tooth, I had to pay much less than I was expecting (a saving of $1,500 or so) and I now feel like a grown-up for taking proper care of my health. I blew part of the savings on the latest Rowan magazine - no yarn, so I feel like a very virtuous grown-up.
