It is necessary to make the appropriate markups in order to hang an object on a wall that has pre-drilled fixing holes. The best course of action would be to mark the holes for drilling and attach adhesive tape on the object beforehand. Next, mark the location on the wall where you wish to hang your item with tape and drill holes in it in accordance with the markups.
9. Defence against dirt
To prevent dust from getting into your eyes and face when drilling holes in the ceiling, place a plastic beaker or a bottle with a cut-off neck above the drill. It will cause all of the drilling dust to remain inside the container.
