This is the Must Have Cardigan pattern from the Hip to Knit book, and is made with Manos del Uruguay yarn in Bing Cherry (#M). Since there are no dye lots with Manos, I used two skeins at all times, alternating them every two rows. This sweater was my first experience with totally altering a pattern for a "custom" fit, and I'm extremely pleased with the results.
