The same instructions as in the video tutorial... included here for those of you that don’t have such a speedy internet connection.
I’ll show you the folding with a white sheet of paper instead of a dollar bill so that you can see the folds more clearly. I’ve drawn in all the folds as red dotted lines to make them clear, and I’ve also shown close-ups of details.

Step 1: Fold the Bottom Edge Up, So That the Crease Is About 1/3 of the Way Up the Bill.
Step 2: Turn Over the Bill.
Turn over the bill. The end closer to you should be the doubled over section. Make a crease down the center lengthwise. Then fold in the sides to meet the center line.
Now we’ll make the sleeves of the shirt. Fold the bottom two corners outward like I’ve shown with the dotted red lines. Don’t worry about the precise angle. The right-hand panel shows a close-up of what it should look like once you’ve made the folds.
Turn over the bill again. Fold the top edge down about 1/4" (about 1/2 cm), like I’ve shown with the dotted red line. The right-hand panel is a close-up of what it should look like.
Turn over the bill again. Now we’ll make the collar of the shirt. Fold the top two corners in diagonally, like I’ve shown with the dotted red line. The precise angle doesn’t matter, so long as the corners meet the center-line.
Fold up the bottom edge and tuck it under the collar.
