I change curtains for curtains and think: what idiot used wooden hats instead of normal dumbels to fix supports. In two weeks I tried a bunch of different dumbels from plastic to metal; the diameter of the hole increased from 4 to 12 mm, the depth - to 100 mm but the gardin persistently did not want to hang exactly; today I bought a new pack of powerful dumbels with nuclear screws, spent another two hours... Now I took a knife, pulled out a wooden rod two blades, killed with a hammer - and it just hangs, infection.
