Well done! I got all done and felt a straight pin once. Luckily I pushed the pin part up through the sandwich and holding the pin with my pliers,pulled the end off inside the quilt. I just left the plastic bit inside the sandwich. A safety pin is a bit harder and I hope you didn't have to rip out any stitching. You can maneuver it to a seam, remove a few stitches and hand sew the spot closed.
