I would suggest that he make something he would actually wear. A successful first project...and off he will be a running...at least for making clothes. There are many easy patterns, though they can be a bit expensive. Our Hancock's always has one of the pattern brands on sale for $2. or so. I'd get one of them. I have seen a pattern that makes a simple PJ bottom with drawstring and a v neck over the head top. That might be a good way to start.
As for quilting, it is a whole different mind set, but you already know all about that!
Tell him we are all on his side!
