I was going for an ocean theme so started with a pale green, and then three shades of blue for the pattern. I painted splodges of each blue onto a stamper, and pressed it lightly onto each nail a few times, moving it around as I did so to get the mottled effect. Most of the time I needed to re-colour the stamper between each nail so there was enough polish to move around. I think the right hand turned out better than the left one, and there were a couple of nails that didn't go so well, but for the most part I rather like this mani.
I used my Bundle Monster BM - 510 stamping plate to stamp some sea themed designs over the top in white to finish off. I particularly like the treasure map pattern and the seaweed. I will definitely try this effect again, it's nice and easy and there's plenty of room for mistakes that don't look like mistakes!
