Photo etching can open up a new high-end market for you in many different types of custom gift products. These may vary from etching wedding and anniversary photos to photos of new homes or other architectural photos, to custom cars, trucks and motorcycles, to children, family and even pets. Since few gift shops offer glass products with photos etched on them, you should be able to command a very good premium for these items. In addition to glass, with a little practice, you can also learn to etch photos on ceramic, stone, and even metal.
