I started knitting the mini cardi last weekend. I'm about 9" into the back. I'm using Andean Silk in Barn Red from Knitpicks. I can't wait to finish it, though I probably won't be able to wear it until November! (I'm in GA, and we just ended a month-long stretch of 100+ degree days.)
So far I like the pattern. A bit redundant, but I do like the texture of the moss stitch.
Here is a picture of my progress:
