Blinds with side fixings

[Melroses]

Does anyone know where to get blinds that fix onto the side of alcoves?

Most I can find are top and face. There is no 'top' (dormer) and the face is uPVC or a thin strip of plasterboard.

I have some roller blinds from Dunelm, but that is all I have found up to now. I would prefer venetian.

Would this do? www.blinds-2go.co.uk/wooden-blinds/20973/parchment.html

Oooh thanks. They look very hopeful.

There is also a clip for the bottom for doors, which would be really handy as the whole window opens.
