When I worked on my denim quilt I had a moment where I wanted to chuck it in the trash as well. And I almsot did. My first quilt had been a baby quilt, but this one was a lot larger. So when it came to sandwiching the layers I found I had quite a bit of trouble getting them to line up straight and flat. I think I finally got it to work, but when I quilted a couple rows the top wouldn't lie flat against the back and it twisted up and wrinkled. I also had trouble feeding it through---I had the stitching at like 4, but I get over some parts and it looked like the setting was at 1. So finally got fed up with it, took the quilt, and proceeded to go chuck it in the trash swearing like a sailor the whole way there. My Mom convinced me not to throw it away. Figured out a way to work on it and came out with this nice looking quilt.
