Here's what you will need:
Step 1: Gather some dog hair
Use the dog brush on the white dog to gather enough hair for your beard. Treats may help garner cooperation from dog. They did in my case.
Step 2: Create a Santa beard pattern
Using paper towels, make a pattern for your Santa beard. This can be an iterative process involving standing in front of a mirror with scissors and a pencil handy. (Closing your mouth over the paper towel will help you with the placement of the mouth.)
Step 3: Trace the Santa beard pattern onto parchment paper
Cut a piece of parchment paper and trace the Santa beard pattern onto it.
Step 4: Cover the parchment paper with packing tape
Dealing with packing tape is not fun. Carefully cover the parchment paper with strips of packing tape, so the entire sheet of parchment paper is covered with packing tape.
Step 5: Cut out the parchment paper
Cut out your Santa beard using scissors. (If you happen to have other tools, such as a cutting wheel, you may find that works more easily than scissors.)
Step 6: Peel the parchment paper and add the white dog hair!
This is the fun part!
Start peeling back the parchment paper and place the dog hair on the tape.
I put hair spray on the beard when I finished, just to keep it from looking unkempt. (I didn't want a Duck Dynasty Santa beard.)
Step 7: Pin to Santa Hat
Just pin the beard to your Santa Hat and you are ready to go!
