Before you get started, read these tips from the pros:

Start by avoiding oil-based face paints. They tend to smear, are harder to remove and clog pores. We like Snazaroo (found at crafts stores).
Just dab a corner of a makeup sponge or soft-bristled brush in water and start painting.
Finish the look with sparkle! Look for nontoxic, fabric-based glitter (found at fabric and crafts stores). To apply, dip the opposite tip of the paintbrush into water, dry off excess and dip into glitter. Roll the glitter onto the face.

Skin safe glitter is called "Cosmetic Glitter". Craft and fabric stores may not carry the correct glitter. You can Craft glitter may contain cadmium, lead, phthalate she and may scratch a cornea. Cosmetic glitter is hexagonal cut polyester, and is inert if accidentally inhaled or swallowed.
If you look at the upper right hand corner of this column, you will see a colourful rectangle with a photo of face painting products. This is the FacePaintForumShop.com. The glitter here is skin safe. The prices are competitive, and the shipping is FAST!
