wss. I wouldn't buy 10 of anything unless I knew it was something worked for us. if you were to get a great deal because of buying in bulk, then it's something to consider because many nappy retailers will allow you to return unwashed and unused nappies. When I first bought BumGenius pockets, I bought 5 because I had a council voucher and I *hoped* they'd be good for us, but I only washed and used 2 till I was certain I wanted to keep them. also buying a few different types preloved means if you really don't get on with one you aren't going to have your husband calling disaster on the whole thing.
as for fleece, you won't need more than 1 blanket to cut up. they are massive and you'd get so many liners out of one!
