I love playing with alcohol inks...they react so unique and create beautiful backgrounds. This time I played with them on mirror foil cardstock...you know the really shiny stuff? The results are spectacular. The downside is getting a good photograph. The one I did on gold foil, I couldn't get a good enough picture to share here...although it's gorgeous IRL.
You can see close ups of this one, and my best shot of the other on my blog if you're curious.
