Good idea, except 20 minutes into my dying session with a flotilla tea bags floating blythely around in the sink, refusing to cause more than the slightest colour change in the fabrics, I decided to try something else. I mixed up some gravy stock cubes and poured those in on top. Bad idea. My mum has always sworn that during the war British women dyed their legs with "gravy browning" and drew lines up the back to imitate nylon stockings... that is as maybe but it had very little visible effect on my fabrics. It had rather a strong effect on their smell though!
So much so that George, my young fluffy chap, was very interested indeed when I went to peg it all on the line. So much of the fabric remnants are now extra-distressed and full of cat claw holes from someone who got a bit over excited by the beefy aroma. Lord!
The end result... no change there then!
