Print out the subway art and let dry overnight (spray both sides of the page with hairspray or clear acrylic spray to prevent bleeding).

Spread a thin layer of Mod Podge on the back of the acrylic shape and then on the front of the graphic.

Apply the paper to the back of the shape, smoothing with your fingers. Let dry completely.

Trim off any excess paper. Repeat with additional charms.

Cut a piece of wire. Insert into the charm and wrap, then wrap around the glass.

These will stay on for the night and you can remove when the party's over!
