Jill Erickson of Art Jewelry Magazine demonstrates how to fill a handheld butane torch with fuel. You can purchase butane fuel at a grocery store or at a hardware store. First, uncap the butane fuel can and hold your butane torch upside down. There will be a small opening valve where you will vertically insert the top of the butane fuel can nozzle. Make sure the components are aligned straight up and down. Then, use direct downward pressure to get the fuel into the torch. The fuel can will hiss and then sputter, signaling that you've got a full butane torch. Make sure you use a fully filled torch before you begin your craft projects.
