Save a t-shirt

Every spring, even if it doesn't feel like spring, I like to take some time out and have a bit of a spring clean.  In this case going through my wardrobe, and sending the stuff I don't want any more to the charity shop.
But I have a better destination for an old t-shirt this time - I'm sending it on to 'do the green thing' who save unwanted t-shirts (they also rescue single gloves matching them up with other single gloves).  The 'saved' t-shirts are then sold helping the green thing to continue its great work.  I love this idea.  We should be happier to reuse things rather than just chucking them away.
