curtain/furnishing fabric central London

[RaisingSteam]

We're in London for the day. I need to find some curtain/linen fabric swatches for a client, dull gold, to check against an existing colour. I was thinking of trying laura Ashley knightbridge, Peter Jones Sloane square, as hope to go to v&a too. Is there anywhere else central, I know john lewis/liberty at Oxford circus but would there be anything different?

John Lewis has a pretty good selection of fabrics, probably the best in Oxford Street.
