Cindy,

That's an easy one. Active imaginations, without knowing our limitations.

I hate to be told something can't be done, and sometimes, to my detriment, prove it's possible.

I have to confess, there is a deeper motive at play.

Could you imagine the look on another engravers face, when someone brings one of these tankards in, to match the engraving?

I can. (devil)
