I think this is the second time I have had a 'fiddle about' with making burn marks with a pyrograph tool, this time onto muslin ( or also called calico) cloth and I like the effect. I also tried using a stencil cutting tool which you plug in at the mains. The tip of it heats up and ostensibly it is used to burn its way through the wax card or acetate I suppose as in if you were cutting stencils - I have never tried using it for that. I thought I would compare them.
I was thinking that I might use this as part of my printmaking work at some point.
