I am making a baby sweater from a pattern with no picture. It says
"Pick up sleeve stitches on holder on dp needles. Join yarn at underarm and work to desired length."
What is the desired length? I haven't been around babies in centuries! and have no idea how long their arms are. The pattern says that it is for a 4 to 10 month old although it looks a little small for a 10 mon. Maybe a 6 mon old. Anyone with a baby that age that can measure the length of their arms for me? :??
Also, what do I use to sew the buttons on? I don't want any swallowed!
