I ordered some of Knit Picks' Chroma yarn to test out for colorwork. This is the Turkish-Patterned Cap from Charlene Schurch's excellent book Hats On! I used size 4 (US) needles and Cascade 220 in black and Chroma worsted weight in the mid-winter colorway.
There is still a lot of the Chroma left (see above) so I think I'll also do some stranded fingerless mitts.
The single-ply Chroma was a lot softer than I expected although I wish it was more elastic.
This shows the colors the best. I only did one repeat of the chart before the crown decreases. The decreases are a bit confusing - I started the decreases one stitch before the row marker for the beginning of the row.
