I am quite lucky, I have been delighted with most of the projects to come off my needles. I've certainly had projects that I never finished because they weren't turning out right, but very few that I consider truly disappointing FOs.
My Brown jumper is, in hindsight, a little disappointing. The arms are too long, the neckline is bodged, the colour of the yarn is overwhelmingly samey and the body is a little short. But, and this is an important but, it was my first jumper/sweater and therefore those faults aren't so much disappointments as learning experiences. I keep meaning to go back to it and see if I can fix it to be more my liking though *laughs*
The very first garment I made, which was supposed to be a capelet type thing, came out completely wrong. My gauge was pretty far out, and I was a little saddened, until I blocked it to within an inch of its life, and ended up with a cute shrug that I prefer to the cape *smiles*
Now that I look back through my projects, there are some that I love, some that I like, some that I like well enough but don't seem to wear... But nothing that is really disappointing.
Recently I ripped out the back and half a front of a cardigan I had started, because I knew it wouldn't turn out right at all. I am learning more and more to see when a project just isn't going anywhere - which is something I didn't do well at first. I have other projects that I never finished, but I always felt a little guilty about them.
Of course, finishing something only to be disappointed seems like a much worse fate, so I am happy to have learned when to say enough *laughs*
