Curtain track for sloping ceiling and odd shaped windows

[Aftershock15]

I have some very odd shaped bedroom windows which need curtains. Originally wanted blinds or shutters but they won't work unfortunately. So now I'm thinking ceiling mounted curtain track - but it has to go from a straight ceiling and curve down to a slope for part of it. The curtains will draw up to the middle pillar on the level part.

Can anyone recommend somewhere I can look for a suitable track that has some flexibility so can be eased round the bend ?

Or do you have other suggestions for weird windows - these are not regular at all - one has 5 sides and another 6..

Thanks

Can you add some photos?

Could you use thin-ish steel poles, that would bend to the ceiling shape?

We have a similar problem with a gable window, that has a sloping ceiling either side of the window with no clearance.

I'm going to bend a length of metal so it drops down at each side. Then use rings.

I think bending metal poles and using rings is what I'm going to try. I've seen some that are ceiling mounted somewhere - just need to remember where.
