Here is another tutorial. I was not as concise or clear as I would have liked, so you might want to skip around a lot. Also, though I put these videos out, I’m no expert at Illustrator.
Okay, no more disclaimers. There are two free files with the video. See the YouTube description.
The plan is to tackle each piece of the costume as a tutorial. With any luck, my daughter will have a complete costume by next Halloween.
