Take a pale coloured strip of FP - white, mother of pearl, pale gold. Drip alcohol inks onto it - the brights work well. Move the inks around with some kind of tool - I used the end of a fine straw. I dripped more ink on and blew some of it around.
The colours I used were POOL, CLOVER, and PURPLE TWILIGHT. The finished strip looks pretty just covered in the inks.
If you want to go a step further, take a Sakura Souffle pen, and doodle all over the inked strip.
You can now use the decorated strip in your projects.
