The basic effect here is something you find early on in many beginner magic books, but using
business cards. The cards here are glossy, the trees are brightly colored and easy to see, and you
have almost everything you need to do the trick included. You finish strong with the package, but
giving them a quarter seems a letdown. My suggestion is to get some of those little Christmas
chocolate balls shaped like an ornament. Rather than focus on the presents at the bottom, bring the
attention to the ornaments on the tree and "pull" one off to give the spectator. When you hand them
the candy, you get the same surprise reaction but instead of losing momentum as they open a gift and
get a quarter you can load up and move on as they are looking at their candy.
You can do
this effect with the card signed but it's not necessary. There's no real sleight of hand necessary
outside of the materialization of the gift at the end, so you are free to focus on presentation and
fun.
