toning cyanotypes

Hi:

I was able to tone the cyanotype T-shirts I made and inadvertently
"bleached" in the laundry. I soaked them in a tannic acid solution.

I did get impatient and add some vinegar - this speeded things up but
changed the tone to a purplish brown, instead of a reddish brown.

Will have to fiddle with toning cyanotypes now.

I will wash the T-shirt again and see if the toned image tolerates laundry
detergent.
