For patterns, I started out with
Mama Bird's Pattern. I then adjusted it to the much simpler way of putting it together with
Dianna's Journal.
I've chosen to start out with 100% cotton flannel for the outside (because you can get such cute prints) with 100% polyester fleece on the inside (next to baby's bottom). The fleece will wick the moisture away from baby's skin. For the soaker (which goes between the layers) I've gone with a
hemp/cotton mix as it is able to absorb like a zillion times its weight in liquid and has antimicrobacterial properties. Bamboo/cotton is another popular one to use. These are not as bulky as terry cloth.
I've also done one from an old t-shirt with the hemp insert as well as one with the flannel both inside and out. It will be fun to see which I prefer.
These diapers (fitted) require a cover of some sort. This should be made from
PUL or even wool or fleece. I started out by ordering a couple of sets from
monkeybunsdiapers off of ebay. She has about a two week wait period, but does great work and will let you choose your fabrics. Still, making your own is cheaper and very easy.
As soon as I get some PUL, I'll try making a couple of covers. I need to learn to knit so I can make some wool longies and shorties.....
The links I've provided for things like the hemp and PUL are fairly random. You might be able to find a better deal elsewhere.....
