How do you read a tell tale sailing?

How do you use Telltails?

Telltales can be used on the leech to indicate flow on a non-overlapping jib. As usual, it is the top telltale that counts. Usually there is only a single telltale in the upper 25% of the leech. Trim too hard or pull the lead too far down (or too far forward) for conditions and that telltale will stall.
