Away Waste Knot: When starting a new thread, it is not always possible to anchor the thread in existing stitching. Make a knot in your thread (cut end) and insert your needle from the front of your work at a good distance (2 or 3 inches) away from the point where you wish to begin. Come up from the back at the point where you wish to begin your stitching. Continue your stitching and when convenient, cut the knot and thread the tail into your stitching to finish.
Inline Wast Knot: If you will be stitching in a straight line, you can place your waste knot an inch or more from your starting point but directly in line with your stitching. Your stitches will secure the tail of the thread and when you reach the knot you may cut if off.
