Basically you just take an embossing folder and dab some ink or paint onto it in a bunch of different areas. Here I used Distress Paints (Mustard Seed and Mowed Lawn).
Spray with water. They also suggested Glimmer Mist. Do NOT spray too much. Just a little. This is TOO much. You'll see below. Just 1 or 2 squirts is enough.
Put watercolour paper into the mess and press down slightly. Leave for a few seconds.
Remove the paper. Here's what happens when you spray too much!
This one is much better:
Here's the card I made from that background. I stamped Mike's Gecko and an old Stampin Up! sentiment in "Gathered Twigs", distressed the edges, put on Daffodil Delight paper and placed on a Chocolate Chip card. I also added a bit of burlap and some brads to get some texture in there.
Anyhow the technique is quick, fun and easy to do. You can experiment with different folders, different colours, different mediums (paints or inks), and even different sprays (water, glimmer mist, I going to try some coloured ones just to see what it looks like) so you won't get bored easily with this technique!
