I had so much fun trying this one out! I didn't ever get a great result or one I had hoped I would get but I still enjoyed playing with this and in the end I will probably use some of my other trials as card backgrounds.
I tried different sized distress ink pads, different folders, different water spritzers, and both watercolor paper and cardstock. I did find that the ink didn't spread as well on the cardstock and the mini mister seemed to give a more consistent spray of water.
I love the results everyone got, I need to go back and leave praise.
I have tried pigment ink before, I think from colorbox on my EF and it did stain. Plus it was hard to get the ink out of the grooves. I haven't had any trouble with memento inks.
Here is my finished card. Thank you so much for hosting, Connie! It's always fun to play with inks:)
