I should have bought a stud finder from the beginning but here I am now. I'm worried that the drywall/anchor won't be able to hold up the curtain rod because of the nearby holes I've drilled. I feel like I am seeing cracks on the wall too. I do plan to patch up the anchor holes with joint compound. If I am thinking correctly, patched up drywall cannot be drilled into again. Ended up getting a $13 zicron stud finder, I hope it's reliable for the few jobs I need it for. I appreciate any response regarding my post.
