If you have access to a laser printer or photocopier that can print/copy sharp high-contrast b&w images, you might consider using Press-n-Peel instead. I find it a lot easier to use than photo-sensitive chemicals.

It's a special iron-on transfer film -- you print your design on it using a laser printer or copier (inkjets won't work), and transfer it to your brass sheet with an iron. The black parts of your design stick to the metal, forming a layer of resist.

While the Press N Peel works well, there are other options, including toner transfer using clay coated paper. Works as well, and it's cheaper.

Printed Circuit board making is basically the same process as making a photo-etched part. This link covers several common methods:

I recently experimented with the transfer pen method, and didn't find it suitable for fine PCBs or detailed PE. Besides, the smell of Xylene (even with a fume extractor) was overwhelming.
