I am so glad that you started this topic. A Japanese friend of mine gave me 4 100% silk kimonos, and told me to do whatever I wanted to with them. Two of them were wedding kimonos, absolutely beautiful. I have taken 1 of the others apart, and was going to post the very same topic.
I think that it needs a little stabilizer, but don't know what kind, because all of the fusible stabilizers that I know of, you use with a hot iron which you can't use on silk. So what would you stabilize it with?
