If you have a bit of experience sewing already, you should be familiar with marking and sewing darts. If this is new to you, or you just want a quick refresher, here's a blog post I did on darts.
Here I have marked my darts with pins. This is what it would look like after I pulled the pattern piece off, but before I separated the two pattern pieces. Make sure your darts are on the WRONG side of your fabric! If you have a fabric that makes it hard to tell one from the other, use a chalk mark on the wrong side to help you keep track.
Once you fold your darts and pin them in place, start at the bottom and straight stitch up to a point.
