Obviously I had plenty of things already on the needles, so was never going to cast on immediately. Last week I looked on Ravelry at the projects associated with the pattern and saw this one*; it is perfect. I added it to my favourites for future reference, thinking that it was a project for one day, as I don't have anything in my stash that would work.
But then on Saturday I had a thought. I do have something in my stash that would work; it would in fact be perfect: at Yarndale a couple of years ago I picked up a 5 x 50g purple gradient set from WooSheeps that I've never found a use for. This is that yarn's moment. Suddenly the Dotted Rays shawl has been accelerated up my to do list and the yarn is wound and ready to go. I cannot wait to have it finished. It's making me so happy that I've decided that it's going to be one of my #BestYearEverKAL projects (no, I haven't decided which one I'm swapping out, but as the Antler jumper is currently on the naughty step, it might be that one).
