Leo loves Where the Wild Things Are (and I love Maurice Sendak). We've never seen the movie but Leo has been practicing his "I'll eat you up!" and "Be still!" for weeks.
If you have never read more by him, I highly recommend the Nutshell Library (Pierre!) and Outside Over There.
I used the pattern by Jessica from Running with Scissors, available here. I made size 2, and enlarged the head for Leo's noggin, but it is a bit too short in the trunk. The pattern was easy and thorough (with links to videos for the tricky parts) and includes fox and bear (Ewok) variations.
This suit doesn't include the claws and paws, but I thought they would get in the way trick-or-treating anyway. My machine did not want to top stitch the neck seam, so it's not as finished there as it should be.
I'm not going to bother with adjusting the fit, but I would like to get the ears to stand up better before Halloween. Max's go straight up.
I also plan to add whiskers, possibly give him a crown, and definitely sew some (non-functional) buttons on the front before Halloween comes.
It's no Pottery Barn Kids, but it was a lot less expensive and very quick to make, especially compared to the Rose Fairy Princess...
More pictures to come. :)
