Maybe you've heard of BabyLegs... not real cheap ($12 a pair) knit "legwarmers" or footless leggings for kids... well, we have a few pair of them, but they are SUPER easy to make.
My friend in CA, Katie, inspired/reminded me to make some BabyLegs today. I had some Halloween socks (adult women knee socks) that I bought to turn into BabyLegs. Socks? $1.99 a pair. PLUS, the toes are GREAT doll undies!
