I started on Tiny Boy's Halloween costume. I expected it to take hours to pattern the turtle shell but I did the whole thing in 30 minutes. I do want to go back and re-configure a couple of pieces in the back end of the shell to change the slope there but it shouldn't be complicated.
Here is the first draft of the shell
And here is the boy crawling out from under his paper shell. The actual shell will be attached so he can't do that.
Three Cheers for Halloween!
