I have polygon thinning going in to the next version that makes regular fonts into single stroked fonts... it works pretty well on most fonts including script. Thinning fonts works great for rhinestones.
Just remember that any typable rhinestone fonts have to be resized according to the size of your stone. You can't use one at any other size or it won't work. This is going to end up being pretty limiting if you only stock a few stone sizes.
No, DukeFan, the typable rhinestone fonts in the original post are already made up of circles, which is why I mentioned it as these are very different from what we are used to.
