I'm a big fan of recycling, and sometimes I wish I could suppress my urges to hang onto everything because I might "need" it someday.
Case in point. I decided I didn't like my filing system, which relied heavily on manila folders to keep everything organized. It seemed that every time I tried to pull one of those folders from the drawer the contents of the folder would wind up sprawled on the floor. Yes, I admit that I overstuff the folders, but I just got tired of picking stuff up.
New filing system? Envelopes. Big envelopes. Now everything stays contained. I also started using some of those plastic things with all the slots for sorting. They work nicely for things like taxes, insurance info, etc., that need to be kept safe and sound.
Now what to do with all those manila folders? Thank You tags. I cut the edges off, found a cool typewriter font, and ran them through my printer. Punch 'em, string 'em, and voila! Fun tags. Recycled. Don't ya love it?
