Question about large sliding/folding doors, leading to open air deck with western and city/bay view. Room gets tons of direct, bright exposure and heats up all year long, so no way to go without a covering. What window treatments should I use? Completely overwhelmed with the options, which all seem costly. Ok with a mid-priced option. Want something modern but also earthy and welcoming and cozy. Have no experience with decorating so could use some guidance on which way to go.
