Hi there, this is pretty much how my tutor taught me to make a dart. The only difference is what you do when you get close to the point of the dart. She taught me to do the last stitch or two right on the point of the dart to prevent that little bubble you sonetimes get and then to sew off the fabric for two or three inches and leave the longish thread tail without trimming it. It works a treat every time even for a newbie to sewing like me!

What a beautiful dress! I love it!
