I used the Clean and Simple Stamping Sketch#178 here. I obviously took it very literally in making my nephew's card. Party This Way is the stamp set and again used Big Top Birthday DSP.
Here's my recipe:
Stamps: Party This Way
Papers: Whisper White, Real Red, Temping Turquoise and Big Top Birthday DSP
Inks: Real Red and Temping Turquoise
Accessories: Stripes embossing folder, Stampin dimensionals
