    How do folks cover the _edges_ of metal pieces being etched, so that
    ferric chloride doesn't creep under the tape (or whatever) protecting
    the back of the piece? I find this to be most difficult when curved
    areas are involved. Even if I use a square metal piece, with the
    design well inside a border, there is still an interface somewhere
    between the edge of the design and the tape. 

Thanks in advance!
