How to shave the back of neckline (without a mirror!)

Step 2: Line up baseball cap bill

Once you have tacked the hair, its time to get that neckline!  Take a baseball cap.  Its helpful if the bill is nice and curved.  So if you are going to use your fancy limited edition, never been worn, tags still hanging on the top, silver hologram sticker still on the bill, black and white Lakers hat, id rethink that.

Place the bill across your neck and use it as a stencil or a straight edge. 

Then start clippin baby!
