I am so loving these challenges! You forget sometimes how effective the basic techniques can be. I have also found I am also using stamps I haven't used for a while.
For this card I have used Hero Arts Cling CG170 Wildflower Garden and Wavy Congratulations F3421. I stamped with Brilliance Pearlescent Chocolate and just touched up the petals with Victorian Velvet Distress Ink. It is still as effective without the colour in the petals as I have made another one uncoloured for my card box. So quick, easy and effective!
