Dear metalsmith friends,
I'm one hundred percent for learning a general range of skills. That is why I always promote doing your own setting. Admittedly, it is a process tackled in steps, but like with everything as you learn more you get more confident.
Engraving is another handy skill. It creates interest and frames a jewelry piece. I like to use engraving on the back of pendants. Start small and practice often.
I recommend an Edenta CeraGloss Fine Yellow Wheel to get the best high polish on the flat engraver. This polishing wheel is a worthwhile investment and last a very long time.
It is available from your local jewelry tool supplier or from a dental tools supplier.

This is a video clip to show the wriggle walking engraving technique.
The best thing to become proficient is to practice, practice and then practice some more.
