For a fine colleague that will turn 50 soon I made a card myself. Just a bit more personal than a store bought one.
I made this card with two layers of balloon, that I cut out of white paper. One serves as a background, the other one has the middle cut out.
Between both layers of 'balloon' I've put a piece of cellophane. Before I glued all three layers to each other, I've put some confetti behind the cellophane.
On the back of the balloon I've attached a piece of cotton yarn and then I glued the finished confetti balloon to a shining and sparkling golden piece of carton.
