Bring the folds together to create the spring shape. You might want to “anchor” the top to the base with a piece of strong double sided sticky tape or glue. If you're using a pretty paper along the base make sure you use strong sticky otherwise in a few days the tension in the folds will pull it off.
I've got several spring cards in my photo bucket if you want a few decoration ideas. I'll also be adding fancy templates here once I've uploaded all of the tutorials from my yahoo site.
