Sorry for the tardy answer. Tracks usually come in 8ft lengths but they can be cut shorter. Each track is hot and must be controlled by switches. There is a variety of sizes and styles of lights available. Suggest you visitsome lighting stores. Two available in my area of Texas are Lamps Plus and Lights Fantastic. Both are chains so they may be in your area.

That's a charming foyer. I can only add that I'm on my 3rd house with a door like that and I still haven't come up with a great solution. I've had a semi-striped sheer panel, a cotton voile panel, and a previous owner had a lace panel. The lace was frumpy. The sheer and voile were ok, but I would take them off in the summertime because privacy isn't an issue then since it's light outside so late (by the time it gets dark we have migrated upstairs). Love the extra light you get with no covering. I have left it coverless in the wintertime too and just ignored it. No one could see anything substantial inside, just the hall, but I don't particularly like the look of uncovered windows from INSIDE at night. I thought about a woven wood shade but I know I would never open and close it regularly so we would be relegated to constant darkness with it down, or it would remain up (and in that case, what's the point?). Good luck, and please let us know if you find a good solution!

I like the roman chamomile with daisetta on the back wall.

Can you show the living area next to the staircase? You have so many color elements going on--golden brown tile, reddish brown steps and banister, a patch of turquoise, what looks like navy and white rug, yellow chair.

A golden sisal with reddish brown binding could work. Or a print or tweed in golds, reddish brown, a bit of yellow. This is a jute:
