The current challenge being set by Linda over on her blog Studio L3 is 'Extreme Masking' which is a technique on page 61 of Tim Holtz' fabulous book called 'Compendium of Curiosities'.
I started off making a mask using one of Tim's Alterations Sizzix dies - 'Branch Tree'.
Here's the colours of Distress Ink I used
It was quite by accident, due to not placing the negative mask in exactly the right position, that the white outline was created. I thought this looked at bit like moon shine, so hightlighted it with some Crystal coloured stickles and coloured the moon in the same way.
In the first photo you can see the mask itself - I really like how this turned out so will be using that some time too.
Thanks for looking!
