Hi, sometimes I find that checking "fill shape with stones" puts the stones inside the letters thus giving you only one line insted of outlining the font.
Also, there are specific fonts for rhinestone desugb that do what you want. Check out some of them herehttps://www.google.com/search?q=fonts+f ... ZZqAG0M%3A
there are several videos on making rhinestone templates using scal on the web.
Inkscape does a really nice jog of single line for rhinestone using interpolate subpaths, there are 3 great videos on how to if you have and can use Inkscape. Here is my favorite. https://www.youtube.com/watch?v=imXr7DyY-sM
Hope this helps.
