I used Bernat's Softee yarn in Baby Denim Marl. It took a little less than one 4-oz. skein, and I used size 6 needles.
The top portion of the sweater is Seamless Yoked Baby Sweater by Carole Bareny and the body of the sweater and the sleeves and the button-band were from this pattern: Free Knitting Pattern: Feather And Fan Baby Sweater by Lion Brand Yarns. I knitted the sweater in stockinette and not Feather and Fan.
I knitted the sleeves the way the pattern says in the Fan and Feather, because I didn't have to pick up sts and knit them in the round, but the sleeves were knitted simultaneously with the body of the sweater. I had to seam the sleeves when I finished with sweater.
I'm real pleased with the finished sweater and I can't wait to see my grandson it in.
