Here are two single line versions of the borders here. These are for use with markers or gel pens. 🙂
The download is a zipped folder with a layered svg file for use in SCAL2 and two single layer files for use in either version of SCAL. These files are for personal use only. Feel free to link to this post, but the files are not to be shared or distributed in any way.
Download the files from here.
