A professional drywall finish has smooth seams and corners. A few tricks will help you to finish your drywall corners like a pro.

Fold the tape in half lengthwise, fit the crease of the tape into the corner, and press firmly so that the tape extends from the corner onto each face of drywall. Press the creased joint tape into the corner for a tight fit.
