So the blanket wasn't really big enough, and I did have 5 balls of wool left (and some odds and ends), so of course it had to get bigger. I picked up stitches and extended it log-cabinwise, then added an icord edging. I don't know if it's how you're meant to do an icord edging but it seemed to work!
Mum's birthday Shetland shawl grew pretty quickly too - just over 10 days of knitting then a day to block it out. I love the way the colours wave in and out with the Old Shale pattern. It was great to do and I think she liked it!
