Making Resin Plugs

So my need to jump from medium to medium is rearing its ugly head again, and the new project I have to try is making resin plugs.  I don't have gauged ears, but I know people who do and think there would be a good market for them.  I found a video on YouTube that shows how to make glittery ones!  Now I just have to get myself some stainless steel hollow plugs to start with!
