- Martha appears to have used gingerbread and it looks like Susan used sugar cookies. This difference caused the difference in shapes of the reindeer. It looks like they both used a gingerbread man cookie cutter shape (see...it's an up-side-down man), but Susan's sugar cookies filled in more as the cookie baked (and/or maybe her cookie cutter man was a little more squat than Martha's).
- I'm not quite sure what happened with the icing, and why Susan's is black. Last icing color in the house? But even with the black icing, it's not all that bad.
