I agree with everyone here...keep it and realize that you have already learned from it. You can recognize what you need to do differently on the next one.
My mom has my first quilt, and unless one of my siblings REALLY wants it when she is gone, I would love to have it back. When I gave it to my folks, they didn't care that it wasn't perfect...they loved it because it came from me. So...be proud that you finished it, and use it or not, you can look back on it and remember how good it made you feel to be working on it...and completing it!!!
