First you need to get some sparklers, all kinds will work well. The best time to take the picture is at night so you can see the sparkle. You might need experiment with the shutter speed. To get the best picture if you finish "drawing" you picture keep going over it so you don't have this long trail. Also if your doing your name you need to do it backwards. Also don't turn if you need to take a step, or it wont show up.
