This is somewhat off topic...but since Missi brought up raveling...
To try and do our part we do our best to recycle, cut down emmissions etc. We walk more, drive less. I've also started hanging my laundry out to dry rather than use the dryer. Not only has it saved us from $25-45 per MONTH but it saves our clothes. I still do use the dryer to "shrink" any fabric that might, before cutting. But, when I use the dryer on clothing I get a good amount of lint. Probably a small handful from each load. I expect it's from the clothes rubbing each other and the inside of the dryer. So, not only does hanging clothes out to dry help save energy and $ it also extends the life of your clothing. Just thought I'd share. :>
