Hi Folks -

Does anyone know a commercial source (or very easy way to make) shadow
masks?  I don't need excellent resolution (10 um holes or even 25 um
holes would make me happy) or complex patterns right now; I just want to
try something out.

I'll summarize replies back to the list.

Thanks very much!
