I was able to complete one wool diaper cover before Silas was born and am just a hop, skip, and a jump away from a second one. I have to admit that we've been relying mostly on Thirsties, though. The wool is in rotation, but really only gets used when our two Thirsties are in the wash. So far I've found it to be inconsistent in containing wetness. There have been instances when he's been both wet and dirty and I'm amazed that nothing has leaked through, but then there are other times when his diaper is not very wet at all, but it did soak through. Maybe it's the fit? The tightness of the stitches? The fact that I didn't lanolize? Effective or not, they sure are darn cute.
