I do think the tight twist of this yarn allows the traveling stitch to clearly stand out as it spirals around the hat. Issues with the pattern: I missed a few decreases so the top closure was not as smooth. I should have cinched the hat at 12 stitches. I do realize that a non-knitter will probably not notice what to me is a visible error.
The hat took less then a skein and as I do like the colors, now I need to find another yarn that I can combine with it to knit a second hat.
