What you can do with empty plastic coffee can?

I use mine to store dried used coffee grounds for the garden. Definitely label it so it doesn't get used again.

There are a lot of good ideas online. Here are google's images when I search then use the image tab on the results page. To see the picture larger click on it. To see that page that it's on for possible directions, click on View page. To go back, click your back button then use the X on the picture to see the rest of the images again.

There are some nice bird feeders on here made with coffee cans.

I use them to pour a amall amount of paint from gallon can when painting. Much easier to hold into. Ive alao used them for seedlings once they get to a certain size. Like Linda said there are dozens of ideas online

Place fabric on coffee can use as a base for fall flowers

One thing I do is cut them up and make plant markers for my garden. Another use is cut out an appropriate shape, use a paper punch to put a hole in one end and make key tags, marking w a Sharpie or printing a label w a Brother or similar label maker.
