Why bambood shades at all? If they are for light and heat control solar shades are much nicer choice and the bonus is you get to keep the view and IMO drapery panels that can’t possibly hang properly when closed are a cheap look

Patricia since it appears (by the OP's screen name) that this may be for looks only, typical homeowner concerns may not be at play. Or if it is for the OP's own home, maybe they want that look for the warmth and texture and maybe there isn't a view worth preserving.

RT Staging - I've been on the hunt for woven wood shades for a while but not specifically bamboo and my requirements are pretty specific. Prices are very high for what I want in my window size. Check Overstock and see if you can get something that fits.

For bamboo, Overstock has some, and Amazon has a raft of them at various price points: https://www.amazon.com/Blinds-Shades-Bamboo-Window-Treatments/s?i=garden&rh=n%3A3736181%2Cp_n_material_browse%3A2241568011&page=2&qid=1551622507&ref=sr_pg_2

What DLM said. And adding that I got some inexpensive ones once for another home I had, and they are not worth much at night to block anyone looking inside the house when the light is on, (unless lined!) so bear that in mind. If you're not handy and can line them yourself, it starts to get expensive fast.

Natural attractive well made woven blinds are going to be fairly expensive. As DLM, I have shopped around quite a bit. The inexpensive option would be to line and/or decorate some cheap ones yourself, but I'm not that interested in being crafty. YMMV. Lots of ideas online if you are.

Smith & Noble makes inexpensive bamboo shades. We used them in a beach house we designed; owners had a limited budget.
