I've masked the semi-circle, stamped the flowers and leaves then sponged with Soft Sky.
The sentiment is white embossed onto Fresh Fig. The balloon is Powder Pink on Powder pink then sponged around the edges and given a coat of clear Wink of Stella. The Wink of Stella just won't show up in the photo but looks good in real life. The balloon's been layered to give it some strength and height and the tassel gives the vertical element from the sketch.
