Here is a swash to use with script fonts. I tried this with three different fonts, and all I needed to do to make it work with them was to rotate, size, and position it. If you want a smoother connection you can edit the nodes in Inkscape or SCAL2. Here is how they looked with just sizing and rotating.
Here is what the swash looks like by itself.
This svg file can be used in either version of SCAL. This file is for personal use only. Feel free to link to this post, but the file is not to be shared or distributed in any way.
