Making Point Counting Transparencies

There are numerous ways of making transparencies:

Draw them by hand onto overhead projector transparencies. A very fine drawing pen and permanent ink works best.
Photocopy them onto overhead transparency tranparencies from some other original. It can be hand drawn, computer generated or simply a piece of graph paper.
Print them onto overhead transparencies from a computer.

Tranparencies that will see a lot of use can be protected with a thin sheet of Perspex.

Postscript files to draw grids on a PostScript printer can be downloaded.
