Here's a summary of its production:
take measurements of your subject,
try it on with the preliminary hood,
make the wings and tail feathers,
put it on.
We decided to abandon the idea of wearing the feet at the zero hour. The tail didn't last long, as it kept tapping the back of her heels as she walked. One person thought she was a penguin. No one else bothered to comment. Oh well. She looked great, and felt great, despite the upset tummy in the morning and having to come home from school for fear she was actually ill. I told her the costume might smell a bit funny since I couldn't very well put the cardboard wings and tail through the washing machine. I did the best I could by hand. Overall a successful Halloween, and we even carved the pumpkin and toasted the seeds.
