I'm making a shrug for my friend's 3 year old daughter. It's a surprise for both of them, so I can't ask my friend her daughter's measurements. I used this website for most of the measurements http://www.yarnstandards.com/headsize.html
I have it all figured out except for the upper arm measurement. I couldn't find it on the site. So I am guessing 6 inches, so 8 inches for the sleeve. Does that sound about right to anyone?
