My two boys are actually pretty neat and tidy....as far as small boys go. We bought the ladybug apron a couple of years ago in San Francisco after a trip to The Discovery Museum (if you find yourself in SF with kids, you MUST go there.) I made little A a star apron using the original as a template from fabric I bought here. The design involves a little tunnel for the twill to go through around the side through to the back so the neck length is completely adjustable.
My creation doesn't have a little pocket on the front like the original though. Maybe little A is jealous? It makes a good gift if you need that sort of thing.
