How do you measure?
 

It never fails, I can never measure inches correctly. The tape always slides or moves in between my rolls :o

How do you do it? One time I'm down a couple of inches. Then I pick up 6. In one area. that's not possible. So I haven't been measuring because I can't do it right.:(

Another way to measure is to use the pant-o-meter... If pants too big, you've lost inches, simple as that...
