This is my first time joining the Retro Sketches Challenge. It only seemed appropriate to pick the Retro Fresh DSP to make it!
For the balloon, I stamped the image from the Big Wish set with Versa Mark ink on the patterned paper. That made the balloon show up just enough to cut it out by hand. Then I shaped it slightly and coated it with Crystal Effects to give a nice shiny 3d look.
