Here's that completed Jaywalker sock (the first, top down one). It might be a while before I get round to the second sock.
Pattern: Jaywalker by Grumperina
Yarn: Angel hand-dyed sock yarn, colourway 11
Needles: 2.5mm dpns (2.25mm for the ribbing, 2.75mm for the tubular cast on)
Modifications: tubular cast on, size enlarged to 92 stitches round (I added one to each straight section).
I don't think it really needed the extra 8 stitches. Switching to 2.5mm instead of 2.25mm solved my size problem. The toe-up Jaywalker I'm doing now is on 2.5mm with 84 stitches and it seems fine. I think I overcompensated.
Here's the silk top I mentioned:
It's a lovely colour, but far too big. I'm going to treat it as a big swatch and do lots of measuring before starting again. There's now a Glampyre pattern for Hip Knits silk, so I've bought that and while I don't think I'll follow it exactly (I'd need more silk and I'm not sure a keyhole neckline would suit me), I will use it as inspiration.
