Is it okay to drool on silk?

We learned how to spin silk in last weeks spinning class. Check out these silk hankies that "accidentally" came home with me. (*sigh) This stuff has to stop jumping in my bag, seriously. This is a silk hankie from Chasing Rainbows, the same hankies mentioned in knitty article here — and here (this also gives instructions on how to spin silk, do not ignore the advice on moisturizing your hands — trust me.).
