care and feeding of silk?

[thanate]

Question for those of you who work with dupioni-- do you treat it as dry clean only, or has it held up to washing? I am wondering if I should fight my habit of serging and machine washing/drying everything that comes into the house (ok, there are some other exceptions) for fear of ruining the lovely stuff, rather than washing it now for fear of it shrinking later on due to potential hand washing.

Opinions?
