Summarize this article:

You can find paracord hanks in most outdoor or climbing stores, or online. Buy a hank of paracord in a color you like. One of the advantages of making a Slatt's Rescue Belt is you don't need to measure out a specific amount of paracord before starting; you can work directly from a hank. To add multiple colors to your belt, buy a patterned hank of paracord with multiple colors already in it. For the Slatt's Rescue Belt, you can only use one hank of paracord. Hold the flame of a lighter to the starting end of the paracord for several seconds, melting the rope and preventing it from fraying or unraveling. Only melt the working end; do not worry about the finishing end of the paracord yet. This will seal off the end and prevent it from fraying. Insert the melted paracord end beneath the bar of your first belt buckle half. Wrap the paracord around this bar in an overhand direction, pulling it back up from beneath the bar again to create a full loop. Make four loops for a standard belt buckle, adjusting based on the width of the buckle. Note that wider buckles will need more loops while thinner buckles will need fewer loops. You can use any kind of belt buckle for this project. A metal one or a plastic side release one will work. All loops should flow in the same direction and should be slightly loose so that you'll be able to manipulate them later on. Leave at least 2 or 3 inches (5 or 7.5 cm) of excess paracord hanging out from the belt buckle bar when you finish wrapping these starting loops. Tie a tight, overhand knot from the excess paracord hanging from beneath the buckle bar. This knot must be tight to prevent the cord from unraveling. Adjust the wrapped loops as needed, pulling the working end of the cord back out, so that the knot lies snug against the buckle bar. Note that the loops should still be somewhat loose.
Buy a hank of paracord. Melt the starting end. Loop the starting end around the belt buckle four (or more) times. Knot the starting end.
