Finger puppets are fun storytelling devices that provide hours of imaginative play. With a mere wag of a finger, your puppet comes to life and begins its theatrical performance.

Your puppet’s persona is predominately determined by its design. Is it big and clumsy? Slender and refined? Jolly with a knobby nose, or nervous with beady eyes? By adding electronic components — LEDs, a battery, and a switch — your puppet can blush, turn yellow with fear or green with envy, or have its heart pulse in excitement.

The circuitry for each puppet can be sewn by hand (or machine-stitched, if you prefer), so grab your LEDs, and let’s bring a few puppets to life.
