    Elizabeth, Use a fine (2 mm) diamond coated drill bit in a jeweler's
    drill press.  Make a dam for water around the hole with an oil based
    clay.  The Drill must be constantly cooled, by drilling through the
    water.  Work slow, go up and down regularly.  You'll get a feel for
    the cutting of the bit.  Another more primitive, but equally doable
    technique is to use the sharp corner of a  file, with kerosene as a
    lubricant, hand twist grind a hole into the glass.  Do half from one
    side and half from the other side.  This  technique will take a
    little longer, but it is immensely satisfying.  Or if you get a 1/8"
    spear point glass drill bit, you can do the same thing quicker. And
    you can  use any kind of drill at a very slow speed.  Again kerosene
    is needed as a lubricant.
