I gotta say, the last option with the bay window curtains sounds pretty awesome. They must look fantastic in that room! I'm curious, why are you selling them? They seem to be in excellent condition and less than 3 years old. I've been browsing online for some curtain and blind options for my new house, and I came across one website. They have a wide range of choices. Here's the link: https://www.direct-fabrics.co.uk/
I hope you find the perfect buyer for your blinds and curtains. And if anyone else has suggestions or experiences with buying curtains and blinds, feel free to share.
