This is a card I made for a Shimmer Paint Technique Challenge over at Stampin Addicts and for a Stamping 411 sketch challenge.
All of the Old Olive card stock has been spritzed with a rubbing alcohol/shimmer paint combo. All of the stamping has been sponged with shimmer paint prior to stamping. So it's hard to see, but all of the green on the card has a nice subtle shimmer to it.
