Redoing window treatments

I've got some problem windows that are only a problem when it's fall & winter since Katrina took away 25 trees on my lot that used to block out the sun. This kitchen window below is a huge glare problem. There was a 200 year old water oak in front of window. Water oaks don't lose their leaves completely till March, so for 14 years this was never a problem. I don't want to hide the pretty trim around the window and I still want to be able to look out that window. I bought a long piece of plastic molding, which I can easily shape to the half circle of the window. Attaching it is my dilemma as well as making a commitment to fabric. I plan to make a balloon type shade that can be raised or lowered.Below, this 17 foot expanse of windows has blinds. It was never a problem with too much sun those 14 years before 2005. Now in the fall & winter, even with blinds closed, the glare is horrific. If I could just cover a couple of these windows a little more, but also be able to look out when needed to see my pond.

My plan is to find some type of 16foot + length of solid PVC tubing...I hope, I hope... to go across this expanse. Above transom windows. On rings, so the panels slide easily. Remember these stationary balloon puff thingies from my TV room? Never put them back up.

They are bronze colored dupioni silk, and consist of 2 180" lengths, folded in half and made into stationary balloons. Now I've taken them apart, cut the 180" ft lengths in 2. I bought white lining material, plan to sew all together. I've got to find a long fringe, at least 5 " to attach to bottom of panels as I need more length to cover the transoms.

When finished, I should have a 90" wide panel at each end of above room. Each 90" panel will cover 2 windows. And block out a little more sunlight, I hope...I hope..

So for the past 3 years, I've been saying I need to do something to fix these problems. The time has come, I'm on a mission. Please give me any advice, thoughts, tips, or better ideas to fix these problems!
