When you re-tuck the fold you’ve been working on back under the collar, you’re
done! It should look about like this. With the basic shape, the collar and
the sleeves, it should be recognizable. Once youve done a few, you can try
folding the whole thing into the reverse side, leaving the obverse side out.
(Like I said, I think this looks better. This is especially true with 1
dollar bills where the edge seal on the reverse under the collar looks
a little bit like a necklace.)
