Let’s have a do-over on the blocking here. I picked this shawl up this morning (deliberately) before it was bone dry: I’m going to rinse it again and smooth out the bottom edge rather than trying to have the pattern end in points. Knitpicks’ merino/silk heavyish fingering weight was a bit too bulky for that.  The points just weren’t crisp enough for me, and as I ran the wires through last night I was pretty sure I was going to bag them later. But I wanted to see first. A rounded edge is easier to maintain anyway, and it’s not something any recipient should be having to worry about.
I was so sure this one wasn’t going to stretch past maybe 24″, but sometimes yarns surprise you. Blocked, held up, it’s 27″, and I had enough yarn out of my two skeins that I could have gotten it to 30″. Size 9 (5.5mm) needles.
A side note: the fireworks last night probably worked out well for parents of small children needing to go to bed. They started an hour early this year, given the extra darkness.
