Yes, I’m still going on about this apartment! Sorry.
One of the windows is roughly the same as a piece of fabric that’s coming on the boat, approx 1 m high x 2 m wide.. I’d like to use the fabric to make a shade, in a way that lets me reuse it later. It isn’t very sturdy fabric. I think it is cotton.
Could I make a shade as in this YouTube video, hang it up now, and then tack the other fabric onto it when it arrives? What should I be cautious about as I do this?
