I decided I'd try anything once, so had a go at this. I used glossy pink card and managed to 'soot' it without burning through - I found that it was useful to crouch down to see what's happening with the sooting (it's a different story getting up again!).
I stamped into the sooting with a DB flower stamp and added 'best wishes' and 'Happy Birthday' - I'm sorry that you can't read these because they are sparkly black with silver writing and just wouldn't scan properly.
It's not brilliant, but it's the first time I've done this and I think I'll try it again some time.
If you haven't had a go at this, I reommend that it's good fun!
