Whad'ya know, I did have enough yarn after all. Braid Hills is finished and I found the perfect buttons for it. The scoop neck is much deeper than I usually wear but it suits the design.
On Ravelry: Dark and Twisty
Pattern: Braid Hills by Kate Davies
Needles: 4.0 and 4.5 mm
Mods: Two-stitch buttonholes, 12 rows apart
I misread the pattern and started knitting the twisted-stitch chart from the bottom edge instead of doing modified twisted rib. For symmetry, I repeated my "mistake" for the neckband. Started to run low on yarn when knitting the sleeves so I only did one chart repeat after decreases, then a 5 cm cuff. Had the perfect ¾-length sleeves but they grew in blocking!
