Following my tutorial what you will get is a cute 3D brooch. It has a fastener on the back and will look gorgeous on winter clothing, be it a coat collar, jumper, scarf, or a hat and a cap. It may also add a nice little touch to the clothes of your child. You may also turn it into a keyring or a pendant for your handbag.
