I need to put up curtains across a doorway so looking to buy a custom length of wood with curtain track recessed. Something like this:

The only place I found was a curtain shop that wanted 500chf for a 1.8 m length. Of course for that price they would have fitted it to the ceiling.

Any ideas where I can buy this kind of thing?

We found net curtains, normal and blackout curtains in Jumbo for not much at all. We had a few windows to cover, so ordered online to get the quantity we needed. I hemmed them myself, just turned up and sewed over on a machine.

Make sure you know the size of the track - they come in Maxi and Mini. you can also buy clips that hook onto existing curtain bands. Manor sells those is both sizes.
