You can use fusible lightweight interfacing and cut with pinking shears. That is how I have handled it. I made a special occasion quilted purse with it and I did the same thing when I used some Kimono silk for a dress. This technique does make it much easier to use silky/fraying material. I learned this from my MIL who was a seamstress who made specialty garments for women... She made and altered quite a lot of wedding gowns and bridesmaid dresses.
