Just bought a new house and previous owner used lots of blinds and left the fittings but not the material. But from the fittings I can't work out what type of blinds they are! There are 2 different types and I've posted some links to images below. The first two are of one type and the next three are another type.
The first two look like roller blinds but they seem to be partitioned across the window which would mean I would need 3 separate blinds?!
They look like headrails for Roman blinds, but they've cut the cords off and taken them instead of leaving them with the headrail. You'll either have to start from scratch with new headrails or get a curtain fitter to re-string them. Assuming you want roman blinds. You'll probably need to have them custom made. HTH
