The bright balloon birthday card uses a sketch and a color challenge.
First, the sketch is from Case this Sketch#208 here. And second, the color combo is from the Global Design Project#073 here. The colors to use are Daffodil Delight, Emerald Envy and Watermelon Wonder.
Balloon Adventures is the stamp set with some '16-'18 In Color DSP Stack.
Here's my recipe: Stamps: Balloon Adventures Papers: WW, Watermelon Wonder, Emerald Envy, '16-18 In Color DSP Stack Inks: Watermelon Wonder, Emerald Envy and Daffodil Delight Accessories: Balloon Bouquet punch, Stampin dimensionals
