Lisa used two strands of sock yarn - one was Silk Garden Sock and the other one was, I think, a blue Berroco Sox, but it might have been an Ella Rae Lace Merino. We swatched so many that I'm having trouble remembering which one she actually chose. Either way, the combination is fabulous. Lisa added a cable down the front edge. As you recall, two sock yarns knit up at just about 4 stitches to the inch on a size 9 needles, making these yarns lots of fun to play with.
Notice how nicely Lisa's Touch Me scarf goes with the cardigan. Perfect!
