Freecycle is an internet news group where people post stuff that they want to get rid of and want to give away for free. The idea is that it is better to exchange things in the community so that we reuse things and not contribute to adding to the landfills as much as possible. It is not always possible, or worth it to try to sell things, and it is better than donating it to a thrift store because you are certain that the person who comes to pick it up really wants it, and you don't even have to take it anywhere to get rid of it.
Today I did my first freecycle. I needed some chicken wire to keep a cat from pooping in my garden (more on that later.) I didn't really want to buy any, since I didn't need very much. I thought, 'hey let me check freecycle', and lo and behold I got an offer the very next morning. I also put up on the board a kids knitting machine that I didn't want anymore because it dropped too many stitches for my taste. Coincidentally the lady who was going to give me the chicken wire wanted the knitting machine, so that worked out very nicely.
Now I am working on getting rid of and old screen door that I was going to use to make a trellis and a bread machine that doesn't work anymore (you wouldn't believe what people are offering and taking on this board.) Unbelievably I already got two replies about the screen door. One man's junk is another man's treasure.
