I got some bespoke stuff made by sellers on etsy, lamp shades, cushions, throws, roman blinds, honestly it costs less than the shops for some really high end materials like voyage or sandersons and always looks amazing. I've now got some fairly unique pieces which I love.
We have been here three years and done a lot of renovation and I would say don't buy it unless you love it. Just wait, and go without and then get something you know you will love. Even if it takes a year to save up for those curtains, better that than buying something to make do and being stuck with it.
However for soft furnishings I'd thoroughly recommend etsy, some of the people on there are fantastic and the things they can make are amazing.
One of my friends said to be recently " I love this house, it's not just the house, it's Everything in it is so nice" and that's generally because I don't buy off the shelf, I spend ages on line looking for things I like then I have someone make them for me, it's so worth doing.
So I'd say think about it, don't buy for the sake of it, buy because it's something you love.
