I used these polishes:
Here are pictures of the plates I stamped with:
(The rectangular plates are an unnamed brand I got on eBay, just search for "oblong nail plates", I got the 12 pack, there's also and 18 pack)
Sponge on the first layer of gradient.
Sponge on a darker color to continue the gradient.
And stamping time :) I did some leafy flowers all in green to just look like a bunch of leaves, then a rose with part pink and green polish, then the purple butterfly on my thumbs only.
