Angelus 2-Soft is a must-have when working on fabrics such as the sock-liner of shoes and other soft fabrics. When heat-set properly, this fabric medium will help keep your fabrics nice and soft after being painted. Mix Angelus 2-Soft with Angelus Acrylic Paints in a 1:1 ratio. Apply multiple coats until you obtain full and even coverage. Allow paint to completely dry, then heat-set using a heat gun at 300 degrees Fahrenheit for 3-5 minutes. This last step is essential.
