Happy Watercolor stamp is retired but you can do this with any stamp set.
I brayered the background, cut out an oval and stamped image on the oval, Then I cut out an oval in the next size up and layered them, The flowers are accented with stickles.
Balloon Adventures is a new set. It comes with thinlets and stamps as a bundle.
Lovely as a tree.
This stamp set has bee around for use and is one of the most bought set from stampin" Up!
I use the techniqe "brayering"
