I couldn't find any 'metallics', so had a go at laying down a base coat of white, topped with a golden yellow. The result is not bad - although in close up (not to mention daylight!) I see that there are little bits of white on the edges. I could always go over them again. I might have a go at weaving some threads and torn strips through this stuff and see what I get.
I got Tracy Bautista's book, Collage Unleashed yesterday. Only had a chance to flick through so far - too many ideas to absorb at once, and the whole effect is slightly overwhelming, almost chaotic - I think I will have to take time to really study each page and really LOOK, so as not to be overwhelmed by the visual impact of the whole thing.
