Here's the candy jars I've done up for the G-men (garbage men), the glass men (recycle men) and for my co-workers. I do these every holiday with the crocheted toppers matching the holiday. When I first started doing these some years ago, I got funny looks from my family - they wondered why I was giving candy to the G-men and the glass men. I just think it's a nice idea - they work hard too - think about all the crap that is put out on the road for them to pick up. Heavy things, gross things - they get it all.
I also reap the benefits - they are nice enough to put our trash cans and recycle can over the fence into our yard. Everyone else's is left in the street. :)
