I was also having trouble understanding that same step--wondering where the loose edges came from. You did a wonderful job on the entire tutorial and with explaining this step better with this extra information and this picture. Thanks. I was thinking it would be fun to make a small project (a tote bag) to try this project as it looks like it is a time consuming project and want to make sure I enjoy doing it before buying fabric for a large quilt. I love it made with the Batiks like you have. It will look wonderful when done.
