It's curtains for you!

I need some help from those of you who might have decorating suggestions.

Our bedroom faces south and has two large windows that get a lot of afternoon sun. Now that it's getting warmer, the room really heats up in the afternoon and takes a while to cool off in the evening. The room doesn't have great ventilation, but we're working on that. We hope to put in double-paned windows and get solar screens too, but in the meantime, I'm thinking some curtains lined with solar fabric would help.

The main part of the room is about 12 x 12, so not very big. There is a small entryway where you walk in that's perhaps 6 x 6, then you turn left into the bedroom. There are a total of three windows; two of them are south-facing.

Walking into the bedroom. The window on the right opens under the carport and therefore doesn't get any direct sun. The window on the left faces south.

Turning left into the room. These two big windows face south.

After stepping into the room, turning around and looking back into the entry way. Door is on the right (with bathrobes hanging on over-door hooks).

The wall opposite the windows is a nice blue color; the bedspread is white. All of the rest of the walls are cream-colored with white trim on the doors and windows.

This is the curtain fabric I picked out initially - it's backed with a heavy solar lining. I love the fabric but I think it's waaaay too much for the room.

So, I need some assistance with curtain suggestions. I can easily back anything with solar fabric, so the options are unlimited. I confess not being one for lace and stuff, but suddenly, curtains like these are looking appealing. Maybe a solid white solar panel with a white lace overlay? Is that too boring? Is there something better out there? White lace just isn't something I would normally go for, so I'm a little hesitant to take the plunge.

I want to keep the price reasonable, and I can sew just about anything, so if you have an idea that's a little pricey or maybe not quite the right color, I can probably find fabric and make it myself.

Oh and if you send me any curtain suggestions that look like this site, I will never speak to you again. There will be no gingham or ducks, thank you very much. ;)
