One thing to consider is the look of the window frames themselves. Could they be plain or very elaborate? If they are plain the treatment you add will have to be much more ornate to compensate. If you have ornate frames they you will probably should be less fussy in what an individual add to the window, using a a lot material or simpler design of blind or curtain.
For any less ornate frame attempt adding a valance or maybe use curtains along with a lavish tie backs.
The next thing to think about is how much privacy you would like. If you have a lovely view over rolling fields with almost no people coming by, then you certainly dont have such a problem. If you have a busy road with a lot of neighbours and visitor going for walks by then you might want to think about bistro curtains which can stay finished all the time at the bottom but still allow light at the top. That way you will get the light and keep your own personal privacy.
A further consideration is if you need to let in air throughout the windows and have to open often the windows regularly. In this case this specific make mean you have to safeguarded open curtains or sheers with an extra pole or maybe clips to stop them taking off in any sudden gusts connected with wind. You also need to consider in case the blind or curtain likely to get in the way of the window opening.
