Allow for household mould if you are cutting the leather armor from a pattern. Folding the leather around the actual object for which a cover is being made, where the mould is the object, is an option when making a case for a gun, an arm guard in archery, a sheaf for a knife or eye-caps for binoculars. The forms are left until the leather is dried. A Three-piece Mould A three-piece mould allows the creation of items like bags and eyeglass cases without using a gusset. Use tacks to hold it in place while it dries. Tools to Use * Wooden mould * Brass or steel tacks Summary * Make a mould to form the leather to the desired shape * Wet the leather * One piece mould: fit the wet leather armor over the mould * Two piece mould: sandwich the leather between the mould * Three piece mould: fit the pieces inside the leather Leave the leather armor to dry before removing. Heat a pot of water to 180 degrees Fahrenheit, then immerse the wet leather for approximately thirty seconds to a minute, until it darkens and begins to curl
