For right-handers, work from right to left or top to bottom. For left-handers, work from left to right, or top to bottom. Bring the needle to the front of the fabric at A, and pull the thread through. Now, for the rest of your stitches, you can work them more quickly if you "run" them on the top of the fabric, without taking your hand to the back. Go down at B, and, using your fingers on your non-dominant hand (the one that's not holding the needle!) behind the fabric, encourage the needle to come up again at C. Pull the thread through. Work to the end of the line or curve in this manner, and try to keep your stitches straight and even! The more you practice, the easier it gets!
