Things You'll Need
Instructions
Purchase a press sound button based on the size and type of sound device you want. Some devices only play music while others only allow you to record your voice or a particular sound. Some do both. Small round buttons are optimal for small and medium-sized stuffed animals.
Make a cut along the seam of your plush animal's paws, either foot or hand depending on preference. Insert the button in the paw. Place the button more towards the front of the paw so it does not get lost in the toy's stuffing, which can make the device less audible.
Perform a test run on the toy before sewing the paw back up. If the sound device is audible, sew the paw seams to enclose the device. If not, re-arrange the device and do more test runs until you are satisfied with how well you can hear the sound.
