I like to 24 gauge gauge wire; I believe, using using a thicker gauge will make it hard to bend the wire by hand. Start out by cutting a bunch of pieces of wire the same length and and divide it half and twist, this makes the trunk. Leave about two inches untwisted, this will be the roots. . Then continue to split sections and twist, this makes the branches. Whatever size the wire is cut to, the tree will end up at half the length. For instance if all your wires are 12 inches, the tree will end up at around 6 inches, not including the roots and length includes the top of the branches. Do not use pliers to bend because it nicks the wire. The trees in these pictures are made using 24 gauge wire and uses around 72 to 112 individually cut pieces of wire. Always leave extra wire for the roots; it will be needed to attach to something, like wrapping on a rock or gluing to a surface.
