Thanks to everyone for all the suggestions. I was leaning towards leaving it, and figuring out an applique. Then I started overthinking it, and before I knew it, I had the border partially off, and the new piece on, so I can continue quilting. Now, to satisfy my curiosity, I'm going to sandwich/quit that piece, and run it through a washer cycle and toss it in the dryer. I just need to know if I had I left it alone, would it have come out in the wash!!
