Start with a fresh bill of your choice.
Fold the bill in half with the face out.
Fold in half again, this time bottom to top.
Open the half you just folded up and create creases to form a triangle as shown in the next video.
Flip the bill over and do the same for the other side.
Next we will invert the folds as shown in the next video.
Invert the folds
You should now have this.
fold the end of the bill up over the triangular center section keeping the crease as close to the triangle as possible.
Flip the bill over and do the same to the other side.
Almost there.. Now for the fun part.
Start with an inside corner (not the edge of the bill) and fold it down as shown.
Repeat fold on the other corner then flip your bill and do the same to the other side.
All done.. Let's open it up.
Slip your thumbs in the center area like the photo above. Use your fingers to hold the folds you just made in the previous steps in place as you open. This can be a trick with new crispy bills.
The last step as a video, as requested. To get the bill to open correctly you can imagine a hinge at the tip of the triangle (back of the bow tie). As you open you want to keep this section together.
