I'm late to this party, but if you don't sew at all yet, I would recommend finding a shop near you that has some basic classes. Books are very helpful once you have the basics down, but they can't teach you how to handle a sewing machine and fabric, how to place pins or hold the threads, or any of those little details. A couple classes should be enough to get you started to a point where you can navigate a pattern on your own. If your daughter likes loose, desert-style clothes, that's good - not much shaping involved! Here's a really nice example:

Next question - do you or she knit?? Endless possibilities there...
