- You can add a cornice to the bay windows- I like the look of a wood crown molding- I am not a big fan of the upholstered ones most of the time. With the crown hiding your top- you can add whatever blinds you like. You can also "dry-wall" a sofit in that would act as a crown in this way- without photos of your place it is hard for me to tell you what would work best. (see the last picture in the post)
- Eliminate the entire idea of "blinds" or shades and just use drapery panels and sheers. Hang them as high as you can- and take them to the floor.
- The smallest, least intrusive blinds are roller shades. Use roller shades and add drapery panels on top to cover outside mounts.
- Use a cafe curtain in the kitchen area. (like shown in this post.) No matter how awkward the top of your window is, this won't go near it.
- Use Roman shades- have them outside mounted- butted right next to one another.- A fabric valance like the one at the top of the post would give a similar look.
Notice the pictures in this post, and in most nicer design magazines. (these are from House Beautiful) I know that blinds are very functional- but they are definitely not the design ideal in window treatments. You will more often see no blinds at all in nicer homes. So- if you are unable to have blinds- you are in good company.
