I took a one day workshop with Sara Lechner this weekend. She is an amazing artist and does wonderful mixed media textile fantasies. Those 2 I did in the workshop. I used silk paint on Vliesofix, lace clippings, yarn, palliettes, threads, hospital gauze, tiulle, burned fabric and heat damaged tissues etc, etc, etc. It seems like you can use anything!
