You need to do what makes you feel better about this quilt. If it's finishing it for a friend, then do it. If it's trashing it, then do that. I have only trashed one quilt in my life, and it was at about the same stage as yours - all the blocks were made, but I didn't like it and didn't like working on it. I felt better the minute it hit the trash can! Relieved would be a good description. If you do finish it, you will also feel relieved, it'll just take a little longer. So, do what you want, and feel good about it! No quilt police allowed into our FUN hobby!
