It appears to me that the hem area on page 3 of the pdf should be as deep as the "extend to square" area so it faces the "extend to square" area. The video never really showed the back of the hem ‐ at least as far as I can recall.
Is that correct?

Hi Liz,
On the 7.7.4 video at the 3:36 timestamp, Jane flips over placemat #1 where you can see the underside of the hem.
