When I used it, I cut it into strips, laid the strips in hot hide glue until they were soaked, and carefully removed the excess by threading it between two fingers.
Then I laid the strips down carefully, starting at one end and then laying it down SLOWLY, so that it didn't tear or wrinkle. Then I ran a finger that had glue on it lightly over the top to press it down.
Worked like a charm, smooth as..well, smooth.
