A listing of some products that can help you avoid disposable items. Be sure to look at what you have at home already, too! The thrift store can also be a great resource. The products I've listed here are well-made, and are created by small businesses, and not in sweatshops. And their purpose is to prevent the creation of more waste.
Kaufmann Mercantile (some of their products are very expensive, but if you are looking for a smaller item, they have some very well made, ethical things)
Ravelry (a site for knitting patterns, if you are so inclined. My sister knitted me some dishcloths!)
On the Go
Shampoo Bars, Bar Soap
Makeup in recyclable glass containers with minimal ingredients
Organic cotton shopping bags, produce bags and bags for bulk bins
Natural Wood and Rubber Lint Brush (works wonders for getting cat hair off of black performance clothes :)
Just a note: I do participate in the Life Without Plastic affiliate program (so I earn a very small commission off of certain product I link to here and in some posts). They are a wonderful company whose values and mission I support fully. Using what you have or buying used is always the best first choice, but it can also be good to support small businesses and individuals who are producing ethical and well-made products.
