Cute remembrance of how little your babies are at Christmas time.  Unwind the string and cut it to length for your child's size, then wind it back around Rudy's neck.  You may add you child's name to the front (between the hooves) for an additional charge, or write your child's name on the back in ink pen (marker may bleed into the wood).
Words on ornament are:
Rudolph's scarf holds a very special memory of me.  For when you unwrap it, it will be the size I used to be.
