I'm hanging a 19 lb mirror onto a wall using two plastic drywall anchors, each rated at 35 lb. However, I botched some math and accidentally drilled two holes (1/4" diameter) and placed drywall anchors in the wrong location, each 1" away horizontally from where the screws will actually need to be placed.
Do I need to buy spackle and patch these holes before hanging the mirror, in case they are making the wall weaker? I can also just leave the anchors in place, if the external force they exert on the wall would compensate. I imagine the mirror falling out and the drywall ripping away, but I don't know whether that's even remotely possible.
If it matters, the correctly-placed holes will be about 57" apart from each other.
