Not sure about SE1, but I'm told that there's a magical emporium at the top end of Lavender Hill, called something like Fabric World/Fabric Wonderland/World of Fabric, and it stocks everything you could ever want. I'm sure it's got "Fabric" in the name, anyway. Apparently, it's quite a long way up the road, away from Clapham Junction.
Mrs I went there one day recently, and came back with an expression of such elation that it took me back to the days when we were courting.
Otherwise, it's a tube ride to the 4th floor at John Lewis, perhaps?
If you find anywhere local, please put it up on here, and I can earn great kudos with Mrs I.
...if you press it, they will come.
