backgrounds sketchbook - shining stones

On the Next Generation Stampers Yahoo group, Trish Bee is showing us lots of background techniques and suggested we record the techniques in a sketchbook. This is the first technqiue I tried and I have finally put it into a sketchbook. Actually it's the only technique I have tried so far as I keep making more of them and trying different possibilities, like using pearlescent paper rather than glossy photo paper etc.
