I'm having such a blast with my oil pastels, I keep looking for new things to do with them. On this piece I've used them over collage elements and a Neocoloured base to integrate everything together (I hope!) There's lots of metallic/iridescent touches on here too, but until someone invents a scanner capable of registering them I can't show you I'm afraid.
Gail was asking me about grounds and finishing for oil pastels. Well so far I've tried heavy watercolour paper and gessoed mat board. I prefer to work on the board I think. It stands up to more blending and working over. Apparently they don't dry like paints though so you do need a fixative.
