Yep! Happened to me a couple of weeks ago. I searched everywhere for one of several seam rippers I have. Every one was gone. ... plain disappeared! Spooky! So since I need seam rippers all the time, I headed out to Hobby Lobby and bought just one. When I got home, the old rippers came out of hiding! They were in all the familiar places. Yikes! Is my house haunted?!
