I want to show everyone the basic art of deco podge, and how easy it can be. This is just a basic course for beginners. If you would like to make your own seashell as you watch this video, then I’ll let you know everything you need. You need your seashell and make sure the background is all white or either painted white and dry. Some mod podge of your choice, a couple decorative napkins along with a foam brush and or a few paint brushes of your choice. Along with paper towel, water.
