Start by painting on the ink in no special pattern. Use 2-3 colors.
Lay a piece of saran wrap on top and scrunch it up. leave it and move on.
Spray with water
Paint on your ink
Add some saran wrap and scrunch.
Now comes the hard part. Walk away and don't touch them for 30 minutes. If you lift up the saran wrap before it has time to dry you will lose the markings. I have done this technique so many times and I had a hard time with it leaving no marks today. I don't know if it is the humidity or the air conditioner or fans but I had better luck in my work room. In the past I have left the saran wrap on over night and it has been fine but today anything left on over 30 minutes was solid color with no markings. So experiment in your surroundings and don't get upset if it doesn't work the first time. I finally got some to work.
I also tried using Smooch Spray and Glimmer Mists Sprays. I had excellent results. These turned out really good. Do the same thing. Spray with the Smooch or other brand spray and lay your saran wrap on top and scrunch it up. These were after 30 minutes. I've got to say they turned out the best. I think this will be the way I do the technique from now on. You do it either way you want.
Here's my card made with reinkers.
Here's my card made with Gold Smooch Spritz. The sprays seem to make the more defined patterns. Have fun ladies.
