Yes, I agree it looks terrible. since you want to throw it away I will send you my addy and pay for shipping. No way this piggy quilt is too cute! I agree maybe hand embroider some simple piggy tails and use something for a little eye or maybe just leave it. Too cute!
Use clear nylon thread with a small "sock" in the spool and regular thread for bobbin thread. Just do a small zig zag around the edges. You can barely see it and it will hold just fine. Now relax and hand embroider some simple tails on the cuties.
