Here is a compound bow paper piecing and silhouette file by request from the SCAL forum. :) Please note that the strings may be too thin to survive removal from the mat unless you use a really sturdy paper or cut this at a large size.
The download is a zipped folder with a layered svg file for use in either version of SCAL and a single layer svg file. 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.
