Here are some links to buying reusable goods for your home and life.
Wallypop- family products
Lunapads- feminine items
Kelly's Closet- cloth diapers
Green Mountain- cloth diapers
These are just a few. An Etsy, Ebay, or search engine query will result in gazillions of sellers of reusable home and personal items. If you are crafty and good with sewing, here are some sites that tell you how to make your own stuff:
Look around and try your hand at making something! Or...find a seller you like and buy a nice set of napkins, diapers, pads, etc. and give them a try. Most sellers sell a sampler pack that allows you to see how you feel about it all! Give it a shot and see how fun and easy reusable can be :)
