Curtains for large bay window (Sandylands morecambe LA3)

We'd love to replace our old and tangly window blinds with curtains. It's a big square bay so ideally I'm looking for a set of curtains at least 8ft wide and 6ft tall, in fairly light fabric (in both colour and weight), with a tape top as we'll need to mount it with curtain hooks on a flexible track.

I can sew, so a larger size is not a problem (or a different type of top if there's enough extra height for me to cut it down and add tape).

Thanks for reading 🙂
