I want to train my bonsai branches down to give the appearance of an old, tired tree.It's about 20cm high and the trunk is around 8mm thick and the branches tapper from around 5 to about 3mm.
I want to know what gauge or (or diameter) wire I should use, but it would be most useful to the community if there was a "rule of thumb".
Is there a general rule for the thickness of wire one should use to train a bonsai? ie. the thickness of the branch at the thickest or thinnest place.
