Scissors, glue, tape, pens, stapler, etc. My two younger girls love doing craft things and take my stuff all the time even though they have their own. They never put anything back either so it gets used up and nobody knows. The thing that is currently missing that I know they took is my ring that DH got for our 10th anniversary. One of them took it before and finally returned it but it's gone missing again! I couldn't wear it while I was pregnant so it sat in my jewelry box forever. I can finally wear it and they've lost it. Guess he'll have to get me a new ring for our 25th.
