I have made several of these..the raw edge looks awesome and once you FMQ it stays fine. I used 506 spray on the edges as well of frey check. I have also made them with sewing the edges and when I did that I used the elmers stick glue to save money and that also worked great. I left the square on under the circle and that worked out fine and of course a bit warmer. I did use a larger, jean needle to FMQ it. Good luck...you will be hooked!!! I am making another one now.
