This is a big pack of 8 convenient sheets of 12x17, easily cut to your size (note that you WILL need some overlap to successfully adhere it, at least 5mm all around).
Shipped as 8 rolled sheets in a cardboard tube, each sheet measures a minimum of 12x17 cm.
See the PDF document above for full instructions.
With dry film, you apply a piece of film to a clean PCB, expose to a negative artwork printed on tracing paper, drop it in a solution of Washing Soda (Sodium Carbonate) which you can buy from the supermarket for a few minutes, wipe off the unexposed resist, and etch.

This allows a repeatable, convenient, and cheap means of doing high-quality printed circuits with fine traces.
In comparison to the toner transfer method, the repeatability and less chance for messing it up, is the key. It also sounds cooler that you are doing "photolithography" and "chemistry", rather than some ironing.
Please note, that I sell (and use) this for Printed Circuit Boards, if you use it for other purposes, for example metal etching, you are on your own as to process and suitability, I only know about Printed Circuit Boards.
