Step 1. Tie a regular knot.
Step 2. Make the first loop with the under layer. This is half of your bow.
Step 3. Center your loop in the proper bow tie position.
Step 4. Wrap the over layer down and around the bow's middle and make the other loop by pushing the loop in front of the first one and through to the other side.
Step 5. Adjust the loops by pulling the double ends.
Step 6. Untie by pulling the single ends.
