Here are two versions of a rope border. One is for placing inside your own shape and the other is a stand-alone border that can be used as-is or welded onto another shape (ungroup first and only weld the base to your shape). 🙂
The download is a zipped folder with svg 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.
