Re: What's the deal with wool?
I get mine here: shop.diaperparties.com/Sustainablebabyish-l-Sloomb_bymfg_37-2-1.html?AffId=4
You can always start with 2 and see how it goes so you will at least have one in use and one drying. With my newborn, I had 3 covers and have added more shorties and longies since then so we can use those in place of pants/shorts too. Sloomb wool holds its value whether knit or interlock. Once you are ready to size up, you will have no problem selling the covers you've outgrown.
As others have mentioned be sure to use a good fitted underneath, like the sustainablebabyish snapless fitted or OBF. This will prevent your wool from getting as wet which will allow you to use it longer without washing.
If you need to speed up the drying, you can put them near a vent or point a fan at them After washing it is okay to put them on a low spin only cycle in your washer but do not machine wash or dry.
