Hand Knit Baby Girl Sweater

Beautiful hand knit cardigan sweater for baby girl. Notice the detailed pattern. The size is unmarked, so I'm guessing at size and trying to err on the small size. It could be larger than 6-9 months. The sweater measures 11" from armpit to armpit and 12" in length. The sleeve length from the top shoulder is 11" and 8" from the armpit to cuff. The color in the first photo is most accurate. I think the sweater is wool, but I am not certain. This sweater was given to me as a gift when my daughter was young, but she out grew it before the cool weather came. It has been tucked away and never worn.
