Hiya,
If she's creative & artistic maybe she should also see what other courses/avenues appeal to her. Maybe she could be a brilliant fashion stylist either.
What no one tells you is that Interior Design is a cut throat business and you have to be a mega expert in selling yourself. You have to be able to convince people you are brilliant and unless you have experience no one is going to give you a look in. Plus these days with all the tv programmes and magazines available, every one thinks they can do it and just aren't hiring. The best option maybe, if she did pursue this, would probably be to try and get a sales position in the likes of Habitat etc.
