Go to the grocery store and get an aluminum pie tin. They are cheap 
and a good grade for pinholes. Use the sewing needle to make the hole 
and then deburr it with fine sand paper.  The book _Pinhole 
Photography, Rediscovering a Historic Technique_ by Eric Renner has 
good information on making (and measuring) your own pinholes.

For my infrared pinhole camera I actually bought a laser-drilled 
pinhole from Lenox Laser <http://www.lenoxlaser.com>, though 
admittedly that takes some of the "homebrew" fun out of it.

Yes, put it directly behind (or in front of) the pinhole.

Have fun.

Oh, and Happy Thanksgiving to all on the list.
