I found this rather cool video on Youtube, featuring Helen Shroyer of Marmalade Cake Company in Toronto, which gives you hints on how to ice cupcakes in 3 different styles. I was impressed with her suggestion on how to fill an icing bag - something I do need to practice as I'm usually covered in more frosting than the cupcake!
You can see the vid here.
Thanks to Helen Shroyer/You Tube for the screen shot of the iced cupcakes - gorgeous aren't they!
