OK! Let's start with the materials you will need to complete this project. You will need a steel stamping set. This one is from Harbor Freight (http://www.harborfreight.com/). There are many places online that sell these sets.
You are going to need washers. I got this from my oh so kind father-in-law. If you don't have one of those head on down to Home Depot.
Finally a nice heavy hammer and a hard surface where your hammering can take place. I do mine on the garage floor. Don't do it on your table...Your asking for trouble (I only know because I tried!).
The rest seems pretty obvious. You pick out the letters you need and hammer the stamp into the washer. Some tips...Pound your hammer down one to two times. Sometimes if you aren't holding the stamp firmly it jumps and you end up with a messed up letter. Also be aware that the washers are thicker than the jewelry pieces so you will have to do it harder than you would on a thin piece of jewelry metal.
When you are done it will look something like this...
Next step is to take a sharpie (love them) and color in your stamped washer.
It will look something like this.... I know a BIG MESS!!
Immediately after you color the washer you take a baby wipe and rub off the top mess.
That's it! Your done!
Remember when I said I don't have a video for you well I just remembered a good one I found 0n youtube! Here are some videos and a website that were very helpful to me...
