It's interesting because when I do a photo search for hacienda windows, I don't find a lot of results with any kind of window coverings at all! I did find this one though, that I thought was great.

I know..have been trying to get some ideas myself..

I agree I would do floor to ceiling in a traditional Spanish colors with heavy black iron rods.

The one Emily posted looks neat and Good ,

rustic dark metal rods 3/4 to1 inch round with rustic finials; floor to ceiling or to crown; hand with matching metal rings. Open and close with metal rods attached to rings. Linen fabrics in Spanish colonial colors and designs. Please line and also use an inner lining ot ensure they fall nicely. :)
