I did manage to count my stitches, and discovered I'd somehow ended up with two too many stitches. This was easy enough to fudge and a couple of k2togs at either end won't show. Once safety back at home, I finished the lace section, which actually seemed easier to knit than the stocking stitch, possibly because of the fine yarn and the finished shawl is now upstairs blocking on the spare bed.
Meanwhile, I decided that Mum might appreciate some yoga socks (she lives in toepost sandals but gets cold feet) so made a pair using some Lornas Laces Shepherd Sock yarn in Purple Iris from the stash. Superwash wool - very important! Mum doesn't hold with fancy yarns! I used the free pattern from Patons' website and they are a super quick, fun knit. The yarn is lovely - so I've just bought some more!
