I am a big fan of reusable menstrual products. Yes... not shy to declare.. :)
What they are?
1) Menstrual cups - http://en.wikipedia.org/wiki/Menstrual_cup
2) Cloth menstrual pads - http://labyrinth.net.au/~obsidian/clothpads/padindex.html
They are healthier (no worries of Dioxin or other cancer causing chemicals), very environmental friendly and cost saving.
I now use menstrual cup but I sew menstrual pads for friends & relatives… Here is a panty liner I sewn recently. I sewn three of this... Given to 3 ladies to encourage them to use cloth pads instead of disposable sanitary pads. I hope to convert them eventually.. :)
There are plenty instructions on the internet how to make one, here is one of them which is pretty good. Lots of ideas of reusing what is available at home:
