Funny story about the Square in Square ruler. I bought the ruler and book package at my guild's sale table. I had it in my hands and put it down on another table. I had my back to it while talking and during that time someone picked it up and re bought it. She then put it down and forgot it and walked off. When she remembered it someone else had re re bought it. We discovered it had been bought Four times! I picked it up from the first buyer when she set it down. LOL We laughed and gave it back to the first buyer.
