You can use cornstarch and shortening as face paint. The mixture of these two will yield a homemade white face paint excellent for clown faces. In addition, you can color the mix with washable paint or food coloring. To create your face paint, you will need a few household ingredients. You can start by gathering all your materials and spreading a rug/rag down to avoid stains when mixing colors: mix cornstarch, flour, water, and lotion in a bowl. Mix these ingredients well, and ensure the paint consistency is your preference.
