Ok here is a fun new one. I have never measured My hands with a tape measure before and I want to try! I actually got the idea from using it on My feet and comparing it with the ruler I normally use. I found, due to the tape measure's ability to form to the thing you are measuring, that it seems a bit more accurate. Maybe that's just me. So I use it on all My fingers and across My whole hand, and compare to the other hand.
