If you use a Swiffer Sweeper, but don't like buying and tossing those disposable wet pads, you can keep Swiffer wet wipes out of landfills by using old T-shirts, cut into wipe-sized rags. You just fit it to the head of your Swiffer Sweeper, tucking in the corners to secure. When you’re finished toss it in the laundry to be washed and reused. See instructions here: http://www.allthingsgd.com/2014/04/reusable-swiffer-wet-wipes-made-from-old-t-shirts/  and here: http://www.thriftyfun.com/Uses-for-Old-T-Shirts-Guide.html

For the more creative types, try your hand at making a crochet rug from old T-shirts. It looks great and is very washable. You can find it here: http://www.instructables.com/id/Make-a-braided-t-shirt-rug/

T-Shirts in good condition:

• Donate to a thrift shop
• Make into new items: http://www.homemadehomeideas.com/28-innovative-ways-to-use-old-t-shirts/
• Sell or give away at a yard sale
• Sell or give away on a material exchange site
• Use as sleepwear

If no longer in good condition:

• Cut into rags
• Old textiles can produce a few cents a pound of revenue for charities that accept them - often Salvation Army is one that will (check with them). To make it easier for them to handle them, label the bag or box of rags as 'For Textile Recycling' so they know at a glance and can set it aside to be baled up and sent away to textile graders for further processing.
