I'm obsessed with silk! I happen to have about 60 silk shirts, but hey, they're all thrifted, and I'm using them as a material. Only problem is where to storage them, so I have to keep them in huge plastic bags in a cupboard.
You can make almost anything out of those silk shirts! Well, mostly I just wrap them around my mannequin in a stupid way like these ones here, and hardly never really sew something new.
