Draw a sketch on a piece of paper. Having a strategy will help you plan the amount of wire you need for each project and will reduce the number of times you need to handle the wire. If this is your first time, begin with something simple such as a basic shape or a letter that can be hung on a wall.
Cut a length of wire and set the remaining wire aside and away from your work area. When working with barbed wire, it sometimes flips and turns unexpectedly -- so it's wise to keep other hazards out of reach.
Grip one end of the wire with a leather-gloved hand. Grip a section of the wire, and then another section with pliers about 12 inches from your gloved hand -- bend according to your sketch. Continue working in this way, one hand on the wire and the other using a pliers, forming the wire into your design.
Wrap the ends of the wire and crimp them -- meaning pinch them tightly with the pliers -- so that they don't come unwrapped.
