The Duets Crochet pattern book features six soft and lacy designs by Kristin Omdahl. You'll crochet them in two lace weight yarns by Filatura Di Crosa,  Superior and Nirvana, using one strand of each yarn held together to produce a sumptuous blend of Superior's cashmere and silk with Nirvana's extrafine merino. The fun and beautiful patterns are for a lace shrug, a fluttery capelet, a sweet web-patterned hat, a cable-patterned cowl, a mini-square lace scarf, and an openwork, sleeveless caftan.
