First I take my sponge dabber and randomly sponge on one colour (I used summer sun) in blotches leaving some white.
Once that is done I take another colour (island indigo) and sponge it on the remaining white overlapping with some of the first colour to make another.

Now take your stamp and fold it so when you ink it up with the darker colour it is only partially inked.
