Also, watch your local area announcements and newspaper ads for church rummage sales. I would ask them if they had anything that they didn't find worthy to put out for the sale and see if they would be willing to let you have them. When they are finished they usually donate the left overs to a local charity. Also the thrift stores throw out tons of clothing that they don't feel worthy of putting out for sale because they may have a rip or missing buttons. You can always ask them to save some of them for you as rags. I have seen dumpster loads of clothing thrown away behind the local thrift stores. They simply don't have time to repair or wash items unworthy of sale but would probably be glad to know that someone can use them.
