Window has plasterboard either side. Someone's attached hook using a tiny wall plug, but it just pulls out because the hook's thread is too slim to make the plug expand and if you were to use a proper plasterboard plug it would be even worse as the hole in the plug is massive.

And of course, the curtain wire exerts a constant slight tension on the fixing.

In the end I've glued a plasterboard plug in with silicone and glued a hook into the plug too but I'm not optimistic. Any better ideas? Might need to use Araldite next!

What I've done is to modify a crosshead screw by drilling a small hole
in the head end and screw that all the way in to a proper plasterboard
plug. Then I araldited the hook into the hole.

You can get screws with holes already in - mirror screws - which might
be easier to modify, or maybe even won't need modifying.
