My daughters went as the caterpillar and the "beautiful butterfly" from "The Very Hungry Caterpillar" book...
The caterpillar costume was pretty simple and I was able to whip it up in one afternoon... I based the shape off of her infant sleepsack. I used yellow flannel for the lining/base, and the outside is a combo of cotton batik fabric and green splotchy-print cotton fabric. I stuffed the sections of the caterpillar body with batting and added a zipper on the side and velcro at the shoulder for easy entry. I also added elastic on the bottom for easy diaper access, but didn't end up needing it for the short time she was in costume.
I also realized that while in costume she would be riding in the stroller, and at 7 months, still needs the seatbelt to help keep her from sliding down
The original costume sack didn't really allow for the seatbelt, so I ended up making what were basically giant buttonholes in the back of the costume so that I could thread the seatbelt to the inside and it would still be hidden.
The butterfly costume was much more time-consuming, but fun to make. I made her yellow dress based on a pink dress I got at a thrift store and took apart for a pattern.
The wings were tricky... I was trying to recreate as closely as possible the butterfly in the book, and the wings are a specific shape... I ended up making 4 different sections with wire, reinforcing each section with a circle of wire taped inside (you can kind of see this circle in the sunlight in the photo of the two of them)... I taped the wire sections together, then covered them with white nylons and attached wide ribbon straps.
I made the design of the wings using colored tissue paper and ModPodge... It's basically a big paper mache project
I really got a new appreciation for Eric Carle and his artwork! It was fun and pretty simple, just very very time-consuming; cutting all of the individual shapes out and having to do the design 4 different times... right/left, front/back... I was afraid it might be too heavy to be on my daughter's back, but it turned out to be just fine.
The hats were made using one of my old red stretchy maternity shirts that I pulled back out of a bag that was on its way to Goodwill... ha! They were based off of one of my infant daughter's hats that has 2 big knots at the top... This allowed me to make antennae out of felt and just slip them over the big knots...
The costumes were a big hit... Most of the people thought my oldest daughter was just a very fancy butterfly, but as soon as they saw my infant daughter, you could see the lightbulb go off in their head as they realized it was the Very Hungry Caterpillar and Butterfly. It was nice to have my hard work appreciated and enjoyed by those passing by
Thanks for letting me share! It's kind of hard to spend a month's time working on a project only to have it be seen for a few hours, then put away in a box again! I'm hoping maybe my youngest will be able to wear the butterfly costume in a few years
