I think there are a lot of ways around actually "doing all the work" as a parent, if you play it right. Like, sit down with your daughter and brainstorm about what she looks like and what she wears. And then brainstorm about how you are going to do it. You can guide her in the "right" direction to the thing's you've come up with, or maybe she'll have a totally different idea that'll also work. And then make her do most of the gluing, etc.!
So in the end, even if it's all your idea, at least she'll feel like it's all her idea, and feel like she make it. :-)
