I'm going to an ATC swap meet in a couple of week, so I'm busy building up my stock of swaps. I love this swirly sun and stars design from I Brake for Digis (save 10% with my SAVE10LISA code), and it resizes beautifully for use on an ATC.
I've coloured it with Sakura glaze pens- the first time I'd used them and wow, they're fabulous, soooo shiny. I then mounted it up onto black card and a scrap of cosmic shimmered paper left over from another project. I'm thinking that when I have time, this image would work brilliantly as a bookmark.
