I have the VB AIO and like it a lot. I also have the Cuddlebuns and like the bikini version. I just got the Honeyboy and Darling Diapers- they look nice, but I haven't had time to make any yet.
I think fabric is a personal choice, look at some WAHM sites to see what diapers you like and then see what they used. I like the trimness of PUL, but I'm making some fleece too because I like the softness of it!
Meaghan- I think you can save quite a bit just by following the VB suggestions, and even more depending on how good a fabric shopper you are!
For instance (according to the One Stop Diaper Shop) to make 12 PUL/Birdseye AIOs you'll need about 3.5 yd PUL (about $8/yd = $28), and about 24 yds of Birdseye (about $3/yd = $72) plus 2 yds diaper flannel (about $3/yd = $6).
So for around $106 you'll have 12 diapers- It sounds like a lot but that's a little over $8 per AIO!!! Oh, add in the pattern price, it's still cheap- $9.75 each. I didn't count shipping because you'd pay that anyway.
That's just a rough estimate, I do diapers individually because I like variety, and I buy material at local fabric shops as well as online so my costs vary. I also use left-over material I have around the house... But bottom line, it's cheaper than buying them, I think it's more fun, and you can customize the pattern to fit your child!
