Best fabric for inserts?

Are you doing pockets then? I like microfibre for the side closest to the baby, inside the pocket, because it absorbs fast, then hemp or bamboo after that. Microfibre doesn't hold wet as well as hemp, bamboo or even cotton though. So once it gets soaked it will start squishing out.
A hemp/bamboo blend is nice because you get the absorbent qualities of both (more so bamboo) with the quick drying properties of hemp.
I've gotten by so far with microfibre, hemp and bamboo. I am able to just use a single 3-4 layer microfibre insert during the day (per nappy!). One of those gets us between 3 and 5 hours. I don't think mine is much of a heavy wetter though. At nights I do a light (2 layer) microfibre insert, a hemp/cotton 2-3 layer insert (it's thin fabric, so a fairly thin insert) and a 2 layer bamboo/cotton fleece trifold (so 6 layers, and bamboo cotton because the fabric shop was out of the bamboo hemp blend. I think it's a 70/30 heavy weight fleece, knit side out) in that order and it lasts us 12-14 hours.

Yup I'm doing pocket nappies...that's a great help thanks! And thanks for the info on approx how many layers for the inserts you use too because that would have probably been my next question!
Right off to order some fabric
