Grey hat in twined knitting

I have knitted a new hat in twined knitting. Not because it was needed due to the weather, but because twined knitting is the most relaxing form of knitting that I know of. It is a plain grey hat, tightly fitted. Instead of my usual beginning, with alternating rows of knit and purl, I used a "pattern" that is rather common on traditional mittens.

This hat is part of testing twined knitting in a rather thick 3-ply, s-plied yarn on needles 3,00 mm. Beside the "ridges" on the surface of the knitting, due to the use of an s-plied yarn, I find the result OK.
