I have sewn many diapers based on the fb design. I got a few of the fb's and tailored the fit to my dd. I have to tell you that the hardest part is material shopping. Hands down, I recommend going with the Tonitex microfleece and a sandwiched pul. I got the fleece from
www.diapershop.com (you have to link a little to find it.) and I got the sandwiched pul from
www.diaperfabric.com. I have tried, and didn't like other microfleeces and more durable puls. The more durable pul lasts through washing but like any normal pul, I found it hard to sew. The sandwiched pul is a sinch to sew and is as durable as can be. I believe that the bummies wraps are made from sandwiched pul. Totally worth the money. I also found long prong snaps at
www.snapsource.com. I really like them. Most of what my dd wears is what we made.
As far as cpf's go. We use them most of the time at home. I bought 2dozen of the bleached 4x8x4 cpf's and 4 bummies super whisper wraps at
www.weebees.com I really recommend them and I LOVE our cpf system. Can't decide which system I like best actuallyl. Oh, I also got a wool soaker for night time and love that. I'm all about simple b/c dh has to help me.
good luck!
