These plastic noses are perfect for use in knit or crochet stuffed animals, and for needle felted animals. For stuffed animals, the nose goes through the fabric, and is locked into place with the washer. In needle felting, hollow out a space for the nose, and then glue it into place.
These noes are a safer option than sewn-on button noses, but there is no guarantee that they cannot be pulled off with wear and tear (and baby or animal chewing!) If making a stuffed animal for a small child or a dog, we recommend that you make the noses out of felt or embroidery stitches.
