Packets vary in thickness depending on the thickness of the veneers and number of layers. These had seven layers of 1/16" veneer (two Ebony, two Poplar, and three mixed),a piece of 1/8" plywood on each side and a piece of grease paper. The total thickness would be close to 3/4".
3/4" is about the thickest I have cut although I have cut more layers (thinner veneers).
You can make several identical copies using piece by piece (classic style). The most I have done is the nine on the drawer fronts of this project.

You will get a lot of answers in my cutting styles blog.
