Oh, darling! You really don't have to feel ashamed with your hands! In my opinion, they are gorgeous.
Maybe they don't look the best for you but they are capable of doing something rare, something that other people wish to be able to do. And more than that, your hands have a lot of stories about the things they created. So when someone looks weird on your hands, just show them what they are capable to do! And then they will search for your attention.
But seriously now, there is nothing wrong with them and I find them normal. :)
