Carl, This is an easy job, but with no easy written explanation.

You want to start 6 to 8" away from the top;

-Using MODERATE pressure, pin the bead to the corner using the center of your palm, upright, while putting in your first nail. Use the smaller holes, and use nails, rather than screws. You'll seat the nail and slightly depress it, but don't overdo it.

-Now, move down one nailhole, and nail the opposite side in the same manner. Continue nailing side to side, in a zig-zag pattern.

Once you've completed this all the way down, go back and nail in the skipped holes, no pressure needed.

As you work, you can check your work by holding a taping knife on edge from the rounded bead horizontally onto the wall in each direction; if the nailing area of the bead doesn't catch on the knife, sticking up beyond the bead or drywall, it will fill & cover as it should.

Be careful as you nail to not press the bead so firmly it completely "seats" on a corner; you want a little mud to be able to squeeze into & behind the larger holes, acting as "plaster keys."

If you have a convergence of tapered joints at a corner, nail above & below the joint area, then go back & nail in the taper; this assures the bead won't try to follow the taper and wind up buckling.

If you do all this correctly, the metal will follow the corner line quite readily, and there will be no "warping" or buckling on the edges.

You may mess one of your beads up getting the hang of this, but at least it's an inexpensive item to tear off and redo. That's about the best I could describe the process; good luck.
