Measure the size of your box, trace an outline of that size on the back of your craft fur with a marker, and cut it out. I made my gnome's beard about ½ of the box's height, but you can do more or less to suit your preferences.
If you’re not using a pre-made Valentine box, cut a slot before decorating (about 4–6 inches long and ½ inch wide). Place it on the top back behind the hat or on the back of the box.
Hot glue the fur onto the box, adding a thick line along the top edge and pressing for about 10 seconds until it sets. You can wrap the whole box or just cover the front to use less fur.
If you are using a bandana for the gnome's hat like I am, then fold it in half to make a triangle and wrap the two bottom ends around the top half of the box. Use hot glue to glue the scarf in place at the back of the box.
Glue on your pom-pom of choice to the top of the hat.
Attach felt heart stickers or other embellishments to the hat for decoration.
Glue the wooden knob or bead to the center of the gnome just below the hat.
