Here's what I came up with, using the super-cute Balloon Bash stamp set, and the colours Bermuda Bay, Basic Black, Whisper White, and Gold:
I wanted the gold confetti to show through the striped balloon, but popped up the middle balloon using Stampin' Dimensionals, so the confetti didn't detract from the wording on the balloon.
As always, the Design Team members at Just Add Ink have come up with some great projects. You can check out the others' here.
