I've never entered one of these challenges, but I'm so pleased with these costumes, I just had to. I know many have done Max and I've seen a few (some amazing) wild things, but here is my craft challenge entry of Max and 4 of the Wild Things:
I apologize for not having any in progress pics, but with 5 kids to outfit and "help", it gets a bit too chaotic for that. Anyway, here's a rundown of what I did. All of their outfits are made out of yards of fleece, except for the dark grey, which is a plain sweat suit. Their hoods are from a basic balaclava pattern I found on line and freehanded their beaks, horns, ears, teeth, etc. I made templates for the girls and they used sharpies to drawn on all of their feathers and scales. Most of the claws are from felt, as is the bird beak. Not pictured, is a red yarn "wig" headband that my youngest daughter had to go with her costume. They even had shoe covers to coordinate with their character. All of the characters were based on this pic from the book:
The Max costume was made using a Simplicity pattern for the basic parts, but highly modified with the button placket on on the front and the hood, which was done free hand. The ears are free hand and the crown is made from posterboard painted gold and leftover faux fur from the tail. The tail is faux fur, stuffed at the end for fulness and the top was just glued shut as turning that stuff was a more daunting task than I cared to undertake. The whiskers are black pipe cleaners running through 2 holes in the hood and twisted. I may be biased, but I think he's the cutest "Max" ever.
