I. Plastic fusing:
I cut thin strips from white and red plastic bag and make a pattern by interlocking the strips together, then using wax paper to prevent direct application, I used iron on medium heat to iron on. The plastic fuses almost immediately and all the plastic strips that were under then iron pan fused together almost immediately. This technique is what I applied to use for one of my final samples to make cherry blossom petals

II. Fabric of thread
We used water soluble stabiliser ( from Lye Nai Shiong, $6/m) to sandwich the threads in between. Then we use sewing machine and straight seams to lock the threads using multiple straight seams and crossed them. We then dilute the whole piece in water until all the stabiliser dissolved completely. Then I used a plastic sphere as a mold and spray starch spray directly on it to form the shape.
