I've been wanting to master the art of colouring caricatures with Artstix. They are widely used in the U.S. but hard to source over here. Anyway, I managed to trace a box and with the advise of some caricature mates, split them in half to make them easier to handle and tried to round the sharp edges off on some rough paper.
Essentially, the Artstix are a woodless colour pencil and comprise of a long square shaped stick of pure colour which can cover large areas quickly. It is necessary to draw on a paper rough enough to take the colour but not too rough to ruin the marker. Also, the paper should be laid on top of a foam pad to stop the surface of the drawing board coming through.
Here are my first couple of tries. I really need to round the sticks out more and find some better paper. Always blaming the tools!
