Well. I breezily ignored the fact that I needed the smallest size in the densest gauge to make this happen until I was ready to cast on. And then I ignored it some more. Until the cables. And breezily ignored it some more.

Go me!

Start with winding CO

No way I’m doing m1r or m1l in this combo, so lifted increases it is.

Gradually decreasing on the sides to avoid the ‘bootie’-look:
4 times pattern straight. From the fifth time, decrease in 5th row for 8 times. Next two rows - work 2 remaining decreases. Join.

3 pattern repeats as toes as written would not stretch over 5cm with my row gauge

Toe as written with one last additional round of decreases

Blocked first on sock blockers until mostly dry, then shoe blockers
