Fits Preemies to 6 months. Also fits many baby dolls! This is fun and fast to knit up! Use worsted weight yarn, and make several of these sets in bright colors. Babies look so cute in bright colors! Easy to knit from the top down. The matching hat is a breeze to knit too. This entire outfit only uses about 6 ounces worsted weight yarn. Use knitting needles, US # 6 and # 13. Good pattern for those to want to knit fast!
