I love gadgets and rulers also. My father and I used to spend hours in a hardware store looking at all of the tools and gadgets and he had his very organized. I have so many gadgets, that unless I save the instructions with them, I forget how to use them and what am I supposed to do with them. I am organizing my sewing area and I found so many different feet and attachments for my sewing machine and I will have to study them to figure out what they are for.
