shaped blinds for angled window?

[muckylittlepaws]

We have some very big windows (so one side of the window is longer than the other and the top slopes triangular shaped). Does anyone have a cost-effective blind ideas. So far we have quotes for vertical blinds and we'll go with that if needs be but I'd like to consider other alternatives first.

Thanks in advance!

Standard blind - shaped to fit into the triangle - used upside down on a pulley - so use a string through hole in the point of the triangle . Works well !seen one on action at a friends house.
