OMG!!!! I am in shock!!!
I cannot believe this worked!! It looks beautiful, and you are so fortunate....bleach destroys silk proteins, I wonder if the tannins in the tea somehow neutrailzed the bleach???? I have seen bleached silk disintegrate.....though you can use hydrogen peroxide on silk safely...
oh well, the main thing is, the final result is lovely. The colors look very rich and the overall effect is fabulous!! Contratulations....
