I am useless when it comes to interior design and I could really do with some opinions 
We've recently had a new kitchen put in and I need some curtains for my patio doors. The walls are sage green and we have white units with a charcoal worktop. I really wanted to go with curtains to soften the look of the room a little (plus I don't like slatted blinds.)
So what colour curtains should I be looking for? I really need to buy ready made to keep costs down and I just can't find anything!
TIA.
