We live and learn - and you called it : you got what you paid for. Grab the 'unsewer' and proceed with hope for the future /// it's your first and it's a labor of love. It was suggested you get a friend or 2 to help - even kids can be helpful .. don't give up your quilt. If you cannot afford to have it quilted again, do a VERY LIGHT spray basting and then some pinning - and Stitch In The Ditch yourself. If the thing is just too thick and heavy to get through your machine throat .. maybe you can do a good job of tying your quilt. But keep it, it has a life in your life.
