I need to put insulation in an attic which has none.

I plan to buy the 23" wide bats and lay them between the
attic joists. These bats are Kraft paper faced on one side.

Which side should go on the bottom?

Any discussion, pointers, or alternative approaches using
batts is welcome. Only batts are under consideration.

Paper down. Before that, make sure there are _no_ gaps
allowing airflow from down below. Including along tops of walls
below. There are many ways to seal them.

Then make sure the insulation covers fully.

For summer, especially in TX, attic ventilation would be a
Good Thing for you.
