my sharpie art is not great, and havent found a good white, Has anyone tried using facepaints on balloons, also there is lots of pictures to copy,

Go here http://www.tigerpens.co.uk/

and purchase Pentel Maxiflo Permanent Markers NLF50-A - these are much better than sharpies.

As for white pens - paint markers are the best - use Edding 750 paint markers

Cheers Darren
