I used leftover stash yarns to knit up two wool hats and two scarves for my 7 mo old great-grandson! He looks so adorable in them!
NOTE: babies should never be allowed to wear scarves when
out of eyesight. Do not let babies fall asleep wearing a scarf. Do not let babies wear a scarf in carseats unless an adult is sitting in the back with the baby.

His mother prefers that I don't post his photo here at KH, since it is more public than Ravelry.
My notes.
