For a long time I have been a great admirer of the work of Carrin Sofies Verden (apologies if I have the name wrong!!) I scraplifted this masking technique from one of her fabulous layouts - I am so in awe of her work and recommend you pay a visit to her blog!! here: http://carrinsofiesverden.blogspot.com/
I don't have glimmer mists so I made my own version of them using pearlex powders, gum arabic and water. I will definitely be playing some more with various masking techniques, it's so much fun!
