Cross your t's and dot your i's

Posted by Sunny on May 13, 2004

I looked it up in my dictionary and ran into a explanation that it means " to deal with all the details when you are finishing something"

I don't get what the "t'd" and "i's" stand for.
and need to know what the "finishing something" mean
does it mean end up something without skipping any trivial things?

Help me here, guys
