My husband and I were Max and one of the Wild Things (my interpretation, anyway):
The monster sweater and hood were crocheted without a pattern. Max’s suit is an adaptation of Simplicity 2853, an adult gorilla/bear/lion/cat suit. Helpful hint: if you ever buy this pattern, don’t buy it as an online download, unless you enjoy the prospect of taping together 83 letter sized print outs.
Other notable appearances included zombie Billy Mays:
and the zombie Ramones:
Thanks to Sophie Begonia for the photos. By the way, she has a really cool Where the Wild Things Are knitted sock pattern on her blog.
