The one pictured above is Chromatic Print in the Dusky Twilight colorway. I've been experimenting with different crochet stitches, and I've frogged it three times. It still looks great. I need to find a stitch pattern that's worthy of this gorgeous yarn! Perhaps a simple knit in stockinette to let the yarn shine?
Chromatic Print is a roving-style, super bulky yarn in 100 percent merino wool. This is a VERY big ball of yarn -- 9 inches across -- with 118 yards in 150 grams.
And I've almost finished a Not-So-Chunky Guy beanie in K + C Superwash Wool Luxe, another roving-style yarn of 100 percent merino wool. It very much resembles one of my favorite yarns, Malabrigo Worsted. I'll post a beanie photo soon-ish.
