Prefolds or Trifolds & Which Fabric to Use?

[alimumma]

Am wanting to make some prefolds or trifolds for newborn stage (thought about buying fitted but they sound like they are too big and not necessary with all the changing in the first couple of months?)

I was going to use bamboo or hemp but am wondering if this is the best way to go - some people say you don't need the absorbancy of bamboo but then I figure I can use them later on for boosters? Plus the feel of bamboo is so nice.

Secondly, prefold or trifold? I believe that a good NB cover is paramount (ie Bambino Mio or Bummis) so wondering if a prefold or a trifold of 2 layers (ie 6 folded layers) would work best?

Any advice appreciated.

Thanks, Ali
