Our challenge is INKY FINGERS *smiles* I was going to do an alcohol ink background but whilst rummaging I found some posh metallic inks I've had forever so gave them a dust down.
I started with 4 colours and placed drops of them onto a craft mat. I then gave a few blasts of glimmer mist iridescent gold (You can just use water)
Next I placed a piece of glossy card on top and turned the card slightly (about an inch) and peeled it off. You can repeat this, add mre drops just play with it. The colours tend to get muddy after the 2nd time.
