I've heard I don't need to felt 100% wool to make diaper covers out of it. SERIOUSLY?!
Can someone please enlighten me about what I can make a diaper cover out of (i.e. so it won't leak) and if I need to find specific types of fabric, or to pre-treat them in some way? I was all ready to get a bunch of 100% wool sweaters from the thrift store, felt them, lanolize them, etc...but if I can skip all that extra hassle, I'd be super-happy!
(Currently we use standard PUL covers, but they're leaving marks around DS's legs and I think wool would be so much gentler. Plus I'm interested in making longies too, for cuteness).
