I've just ordered some Acrylic templates for my boy for his birthday and going from Cog'OTwo's stuff know that you need to fill the laser etched engraving with some form of Colour to make them pop.
My question is can this be done using Crayon?? I've ordered a grey tint with storm trooper engraving and have a copious amount of white crayons in the house but little in the way of white paint (except spray but theres no-way i'll let a hyperactive 7 year old loose with a spray can!). would it be a good substitute? they'll never be left anywhere hot enough to melt the crayon and he can have fun scribbling on the templates a bit before he gets to use them.
