I am so sorry that you're disappointed. I think the problem - as others have mentioned - is that thread basting would do a better job of holding your layers together. It is also important to check the back of your quilt as much as the front.
if you ever try the frame/hoop again, I have a hoop that I travel w/ and i will balance the hoop on the back of another chair. That allows me to get my hand underneath to feel how things are doing.
I understand your frustration, you can take the time to fix it (i'm kinda OCD about this and would probably have to do that), you can save it as your first project as a reminder of how far you will go as you complete other projects.
