Wool Longies

Many people I know use wool longies as soakers for their cloth diapers. Truly, I have never really understood how they work. Why does wool act as a cover to a diaper? Why do you only have to wash them every once in a while? Well, I still don't completely understand, but I LOVE these sweet little knitted pants. I'm taking a knitting class with Erica Marsh so I can learn to make them myself. I'm almost done with my first pair! Rhea is going to wear them for her birthday.
