I do not have a junk drawer. I used to have one, but I realize that two main reasons for the draw are (1) emotional attachment to the items and (2) fear that they'll be needed after I discard them. They are important if we think they are, but are they really? I have changed my thinking/attitude. No attachments and I deal with my losses if i ever throw out something I need later.
We had one and it grew to three! Screw drivers, electrical tape, old keys no one knows what they go to, and just about anything and everything. One of these days I will get them cleaned out. I recently dug in there and took out all the AC adapters that go to who knows what. There were 10 of them in there and I got rid of them. Well...it's a start.
I had started with one junk drawer but now have three! There are jar lids, cork tops, various screws and nails, drawer handles, twine, batteries, mouse traps (eek), rubberbands, small candles, little bottles and old tooth brushes...just to name a few. Generally, once a year we will clean them out and sometimes when we do, it feels like Christmas again...."Oh, yeah, so that is were that watch band went!!!"
