This gorgeous cardigan rates an Experienced level because of the use of short row shaping in the collar and sleeve caps. If you're comfortable with short rows, you'll find this pattern a cinch. If you've not worked short rows before, give it a try; you'll find it's not that hard at all, and the cardigan is well worth the effort!
The yarn I used works up at a gauge of 6-6.5 sts per inch in Stockinette stitch; if you wish to use a different yarn, make sure you find one that will match this gauge.
24 sts and 30 rows = 4" (10 cm) in Stockinette stitch
At 6' tall, I used to have a hard time finding sweaters with long enough sleeves. So I took up knitting to make my own sweaters.
