Any worsted varegated yarn, I used a varegated wool similar to Galway. The neckline is square, and the cardi is knit from the top down. It has negative ease, but the ribbing(2x2) is very stretchy, and can be blocked so the fit is looser. The sleeves are just past elbow length. The buttonband is two ridges of garter st, and garter stitch is worked around the neckline(I worked reverse single crochet or crab st on this). Length is hip length.
Suggested yarns: Plymouth Outback Wool, Baby Alpaca Worsted, Galway Paint, Madrid, Parigi, or any worsted smooth yarn.
