Since I've been making a concerted effort at stash reduction over the last year (and will now have to redouble those efforts as the baby is getting the room my stash currently resides in), I resolved only to buy yarn in Sweden if I couldn't get it at home. This cut down the options quite a bit as even Drops is available in the UK.
I did pick up some sock yarn (probably for the resident radiologist, but I do rather like it myself).
The brand is Marks and Kattens Fame and the blend is a standard sock yarn - 75% wool, 25% nylon.
I also picked up a card of darning yarn for a good jumper of the RR.
I've never seen darning yarn like it in the UK - there was a rainbow of colours and a good selection of weights available.
Finally, my eye was drawn by something I hadn't even thought about in years - embroidery kits. It might have been because my friend, in addition to being a great knitter, makes lovely cross-stitch tablecloths and pictures, so we were looking in that section. I was reeled in by the designs in the Permin of Copenhagen 'Scandinavian' collection and this beautiful kit for a tablecloth ended up coming home with me.
I haven't done cross-stitch for almost 10 years, never mind embroidery so it took me a while to get going, but bit by bit, stem stitch and satin stitch have come back to me and a little progress is being made. I'm not holding my breath for this Christmas though!
