Since Blendabilities aren't available, I thought I should try another colouring technique.
No-black-outline Colouring... at least that's what I'm calling it anyway.
So here's a few step-by-step photos & some of my favourite stamps.
I've just used the Pool Party Marker to slightly darken the round ends of the flourish that I stamped with Soft Sky.
Here you can see the difference of adding the coloured outlines.
The image on the left has no added outline, where as I have added coloured outlines to the image on the right.
