I started this sweater right after Thanksgiving and finished seaming it Christmas morning at 1:05 AM. It's made of Berroco's Ultra Alpaca in "Henna" and the pattern is also Berroco and is called "Arthur". It alternates basic stockinette stitch with reverse stockinette on the top half and the sleeves, with a simple garter/stockinette pattern of 5 stripes up the middle that reverses in the center. I had to drop down 2 needle sizes when I made the gauge swatch, using Knit Picks interchangeable size 4 for ribbing and size 6 for the body and sleeves. I also had to add 2 inches length to the sleeves to fit my long arms. I enjoyed this project and the sweater is so soft and warm. It's a pity I can't wear it much down here in Florida! I'll keep it for my holiday visits up north, LOL.
