hi Jennifer, We have green velvet curtains which are sun bleached and other stains are they suitable to be dyed without shrinkage and damaging the fabric. Thank you sally.

Dear Sally,
please look over my article on Fabric Dyeing 101. This will give you the basic information about what kinds of fabric can be dyed. In general, even if the fiber content could be dyed, I have to say that I don’t think your curtains will be worth the process. Sun damage weakens fibers – you may end up with shreds after the dyeing process.
sorry,
Jennifer
