Needle punching and heat setting

To experiment more I punched wool, silk and polypropylene together. The wool and silk were punched onto the outside of the polypropylene which is a heat setting fabric. Once all three layers had been punched together I gathered one sample with thread and the other with dress pins to compare the outcome. The samples where then put in a oven for the required time and temperature. The results were very interesting with their textures changing and shrinking as well as the handle of the fabric changing.
