Crumpet comes to me with a lot of involved and complicated craft plans. He definitely tests my creativity. Once, he saw jousting on t.v. and instantly needed a lance, a horse, and a stable. I've had to learn to sew, , build, draw, paint , and use tape in a myriad of ways at a moments notice. If you present him with a simple craft project, the answer is either no, or yes, but...lets make it better like this. And it becomes very elaborate. And if it's not exactly as he imagined it would be, His Royal Highness is not pleased.
