I have heard of making these with leftover threads and water soluable embroidery stabilizer. You make a sandwich of stabilizer, threads, stabilizer, then sew all over to secure the loose threads. Once stabilized with thread, you then soak the whole thing in warm water to dissolve the stabilizer, leaving you with a thread fabric. If you are going to drape it over the bowl, I would use fabric stiffener, found at craft stores. It dries hard and firm. Good luck and post pics if you do this.
