INSTRUCTIONS FOR A FULL WINDSOR KNOT.
#2. Take the wide end of the tie and pull it through the loop on your neck. Then take the wide end of the tie and wrap it back behind the narrow end.
#3. Now take the wide end of the tie and pull it through the loop across from the side of the previous wrapping.
#4. Slightly tighten it so it is snug, and pull the wide end back over the front of the knot. Don’t pull tight but create a loop.
#5. Pull the wide end of the tie through the loop at the front of the knot.
#6. Slightly tighten the knot. Make sure that the wide end of the tie lies centered and doesn’t fall into the crevice created of the two wrappings.
#7. Give the knot some final adjustment to make sure it is good and snug and flip down your collars. You are done tying the Double Windsor knot.
NOTE: If it doesn't look perfect, undo and do it over again. Practice makes perfect.
Oddly enough the best video I could find demonstrating how to tie a Full Windsor Knot is by a woman... you go girl!
