jars labeled with puff paint or hot glue, then spray painted___ Worked so well!!! I put star stickers on before I spray painted, and then too them off once the paint was dry. I did try some spray paints, though, that didn't stick.
Starting next year, I'm going to keep a jar. Every time something memorable happens I'm going to write it down on a piece of paper, date it and store it in the jar. At the end of the year, read them all and start over the next year. After I'm done with them, I'm going to store them in a memory box for the future me too look at with my children.
