Here is a link
I am not sure if y'all are still needing/wanting any information about what materials to use for mama cloth, but here is a link that may prove useful to you both.www.diaperpin.com
Click on the link for forums and scroll down until you see a section called, Cloth Talk. This section is dedicated to menstural alternatives so there is 20 pages that you can go through and hopefully you will find what you are looking for.
I went through all 20 pages (I think I am a bit addicted to cloth
) and read quite a bit and learned about some new cloth pads makers I didn't know. There is a bit of posting about making your own (along with pictures, details about fabric, and how to) in those 20 pages.
Most say that 4 layers (top layer of flannel or cotton, 2 soaker layers terrycloth, flannel or cotton/fleece mix, and a water barrier of some sort like fleece or PUL) is enough.
I use 4-6 layers of cotton/fleece. As the PP said, it really depends on your flow.
