It combines a marl, taupe color, 100 percent merino wool yarn from Ireland -- that's the recycled one -- with a new yarn, a repurposed Berroco scarf yarn from Italy. Glee, the scarf yarn, started out as a knitted tube, which I unraveled into a ball of self-striping fingering-weight yarn.
The stitch pattern is back-loop single crochet, and I used a 5.5 mm hook.
