We’ve been renovating a house and, trying to do too many things at once, I have ordered eyelet headed curtains for a bay window. I have managed to find ONE product that claims it is suitable for this, however it only comes with brackets suitable for wall fixing. The UPVC windows go right up to the top of the wall so their is no plasterboard to drill into and I’m guessing we therefore need a ceiling fix solution. Do you think it would work if I ordered the pole suitable for eyelet curtains and fixed it with generic ceiling fix brackets? My other concern is whether a ceiling will take the weight of the curtains (they’re linen with standard lining so not super-heavy). I’m attaching a photo to show the window in question.
