When you settle on what you want, the discounts are huge and seem to vary widely among online sellers on a daily basis. There are a ton of sellers and lots of comments about various ones if you search this forum. Once you order samples, you will get tons of discount offers. I just googled fabric roman shades and came up with this site that does a nice job with showing pictures of each of the shades installed on windows, which is very helpful. They look to have a wide selection of styles and prices to choose from. http://www.blindster.com/roman-shades/ Fabric roman shades also offer flat or hobbled styles. Woven woods are always (?) flat I think. Generally fabric will be more expensive than woven woods, but again, prices vary greatly. The higher prices within a line are usually better color/fabric choices. http://www.blindster.com/bamboo-shades/ I think that bamboo shades in a french country setting should probably be plainer and not so textured...i..e just cover the window... don't call out so much attention, like this: But that is not typical with woven woods. Most folk get them because of the texture and casual nature. Too plain may look boring. Will you have drapery panels on the sides too? That would be a way to add more style to a plain shades. Maybe in the office that will not matter so much, but when you get downstairs you probably want more styled. I don't see this as French anything. Of course, there's a lot in between. Just making a point. For myself I found a tone-on-tone offwhite that I am going with for my guestroom. That room I don't really want a full-on wood look, but still like the idea of the woven woods. Another thing to consider with woven woods or any type of shade is cord options. Cordless is great if you have access in front of the window to reach the top well (especially if you lower and raise them regularly). Continuous cord loop is a bit more convenient than straight cord. The bottom of it attaches to the side of the frame and is used like a pulley. Good for kids and pets... no loose cords. Another important feature is top-down bottom-up, but that's usually done for privacy purposes. It also precludes cordless on woven woods (but not on fabric shades). As you can see, I'm deep in the weeds on this subject. I am in the process of figuring out the same issues as you for my two sets of triple windows in the living space. The choices are overwhelming and you have to see lots of samples in person. I've got my choices narrowed to about 5, but I'm sure there are another 20 that would probably be just as good. When I get it down to 2, I intend to go to several websites with a spreadsheet and compare best prices. That's one reason to stick to Levolor or Bali. Everyone carries them.

Be careful with the PB shades. They do not have the mechanism to hold the shades at different heights; you must use a cleat attached to the window frame to hold the cord used to lower/raise the shade. No where on the web site does it say this :(. Since I bought one for a window (middle one) with no frame I cannot use it. I also feel these shades are inferior in the construction: plastic rings, staples in the front of the shades to hold the fabric to the frame. Of course I bought some on clearance and could not return them. Before you buy make sure you check them out in the store. The ones I purchased were not in stores. For cheaper wovens I bought from JC Penny the ones linked below. I really like them. They are tightly woven and you cannot see through them. Not lined, but also not expensive. I got mine from the store. Don't know if the sizes are right for you but check them out! Here is a link that might be useful: cape cod shades

This is where we ordered ours from. They have great prices on Levolor. When you're on the page, be sure to see the extra 35% off. Both Star and Levolor have great service. They come in 84" and even longer. You can get them at a big box store, also, but we had a bad experience with customer service (HD or Lowes, forget which but they have sample books). Drat, just checked the link and all it says is Stardecorating.com. Just type it in and you'll get there. :) Here is a link that might be useful:

Can't speak to the humidity but my mom has had woven wood blinds in her casual eating area for over 30 years. This year during a reno she had to have them restrung but the actual blinds are good as new. They are very expensive--but she is getting her monies worth!! Hers are verticals. I had a woven woods roll up shade in my basement family room when we arrived. It was great for insulation against a picture window in a walk out basement..but the pull cord broke. It was maybe 20 yrs old--just guessing.
