Euros - looks white, turns gold.
The Double Helix site suggests that it will strike and reduce, but apparently - I could not do it delicately enough, and I had no luck striking it. Reduced it instead.
Self coloured, flattened. Attempted to strike - well - maybe got a little strike, there is kind of a blush on the end, and reduced to a deep, rich honey colour.
Next one, added a trail of ivory, and reduced. Par-tay!
Again with the ivory and reduced and encased in this one, and the spiral pressed in.
Must do more with this one. I think this will be a sleeper - people will be unexcited by the white colour, not realizing what fun they will have with it.
