I have always wanted to have a go at soldered charms so I was feeling determined today!! The first two in the picture have come out bumpy but I perservered and the next two I am quite pleased with. The secret I think is to make sure the copper foil is really neat on the front then make sure you brush loads of flux on it then the solder runs freely. Another good idea is to have a damp cloth nearby for when you burn your fingers as the solder tool can get really hot!! But its all in the name of art so who cares!!
