Turquoise on top Red on top
An additonal black layer on top White on top
On the one which had the white on top of the stack the turquoise which was the layer underneath has become muted so it looks more like a teal than the bright turquoise it really is. The red is still bright on this one though. The only one that has an extra colour is the bottom left one which has a layer of black put on the top before the pattern was impressed. Putting the layer of black on the top made the colours seem even brighter where they do show through.
They ended up quite small pieces as I was just experimenting so I haven't made anything with them yet. The weather has been lovely and sunny here which is a nice change after the weeks and weeks of rain we had! Long may the sun shine!
