the technique i used for the batch on top is just patting and blending colors with the cotton pad, the more you pat while it's still wet, the more splotchy and marbly it gets. for the batch on the bottom, i start with rubbing on a pale color all over, then squirt drops of ink and let the drops do whatever they do. sometimes i allow colors to bleed together and push each other's borders around while wet, other times i let a drop dry before dropping another color on top of it.
soon these will make lovely pendants!!
