What do you do with a few spare dollar bills and a twist tie? Fold them into a tiny flower, of course. The Money Twist Tie Modular Flower is one of those charming little models that feels almost like a magic trick — three ordinary bills transform into a blooming star you can actually hand to someone. It's the kind of thing that gets a real smile out of a waiter or waitress when you leave it as a tip.

Don't worry if you're new to modular origami; this one is wonderfully forgiving. Each unit is quick to fold, and the real fun is in the final flourish when you bind the three pieces together and watch them flare open into petals. Grab three crisp bills, find a twist tie, and let's make something worth tipping for.

This Money Twist Tie Modular Flower is a variation of a traditional design. It is a simple model to fold, and it produces four different versions of the same flower. Folded from three one-dollar bills, this dollar-bill flower makes a charming tip for a waiter or waitress. To hold the bills together, you will need a twist tie, or any similar fastening device.
