For two windows in my house, the curtain/d**** rods fell out of the wall and, therefore, left holes in the wall that will no longer hold the nail/screw used to support the rod. One wall is drywall and the other is a very hard, concrete like wall.
How do I fill these holes so that I can re-hang the rod?
Do I fill them with mud, then re-drill the hold in the same spot? I'd like the rods in the same place.
Any other ideas?
