Fire Markers

I started off with some cheap plastic tea lights and some hamster bedding

Next I used masking tape to cover up the flame and sprayed them black

Then I did some crude flames on the tea lights, not a great job but most of it won't be seen, or they could be just left black

Next I removed the masking tape, then I used white glue to add some hamster bedding, when the glue dried I gave them a light blast with the black spray and teased the bedding in to  billowing smoke shapes
