I was reminded about this technique from another demonstrator. I'd forgotten what a cool effect this gives at Halloween!
Project Recipe
You will need a lit candle
3 1/4 x 3 1/4 Glossy Card Stock
Take the glossy Card Stock and quickly wave it over the candle until the glossy side is full of soot.
Next be careful not to touch the sooty side, if you do you will wipe away all the soot. Take uninked stamps and stamp your images. I used a 1 1/4 inch circle punch and made a mask for the moon before I did the soot. I stamped the bats and the sentiment in archival black ink
Once the stamping is done, you need to spray a fixative on it so the soot doesn't wipe off. I used Aqua Net hair spray.
