I have a friend who is in the Peace Corp in Kenya and she has proposed a project to help the women in her area via reusable menstrual products. It has been approved pending raising enough money and the community has made a pledge for 45% of the total budget.
She explains it better than I ever could on the webpage, which I've linked below.

I know many members have been interested in something like this in the past, which is why I am posting about it here now.
