I have face painted at parties, at fund raisers, for fancy dress and more recently painted a simple face on my feet for a competition entry.
I only use Snazaroo face paints.
The colours are vibrant, they cover beautifully and stay put, they clean off relatively easily. The paints are water-based, hypoallergenic and non toxic. I have never experienced any problems with skin reactions.
The range of Snazaroo products for serious face painters is amazing but you can't go far wrong with these kits from Toys R Us.
I prefer to take my time when painting faces and have a practice first. The video shows my first attempt at the butterfly face in the instruction book and a bit of freestyling fun with my ever willing assistant!
