My 7 year old hates for me to keep trying clothes on her when I am making her something new.  So, I decided to try making a duct tape dress form of her.  Making the dress form is a easy concept for an adult model.  However, for even a well behaved 7 year old I would say Don't Try this at Home.  Well, at least make sure you have a nice bottle of wine for you and ice cream for the kid to look forward to when it is over.  It only took an hour to get the shell done but that is still a long time to get a kid to stand still without wiggling while you are mummifying them in duct tape.  Also, the smell of the massive amount of duct tape is a bit overwhelming for an adult and more so for a kid.
