This is the one I did as an example.
Here are Connor's Elf Feet.
Lex decided that he didn't want to draw Elf Feet. He opted to draw Santa, instead.
His Santa is pretty fantastic.
I ended up drawing a second set of Elf Feet, this one with pants instead of an elf kilt.
Uncle Kevin was a good sport.
Nana's Elf Feet are very pretty.
