Hmmm I think I am going through a 'Jackdaw' phase as I seem to be creating all things shiny at the moment, with embossing powders, acetate, and Cosmic Shimmer - this being one of the latter.
Another tag, another size, but on mount board again. I am so glad that I got the offcuts - it really is a nice sturdy surface to work on, and the reverse side of it really absorbs the inks.
I used TH distress re-inkers in lavender and blue for this, then flicked some Cosmic Pearlescence over it with a brush.
I stamped it with a foam stamp (took a chance and bought one second hand and it really is good) then once dry I added the image.
You can not really see the lovely sheen in the photos - but the greyer areas are the shimmery ones. It gives a lovely effect in the light.
