I bought this real pretty knitted long sleeved black chenille trapeze dress and there are places where it looks like a stitch wasn't finished so that I have a couple of holes that don't belong. What is the best way to fix it? I am a little worried that if I don't fix it then I might have an embarrassing problem when I wear it. And it is just so pretty that I don't want to have to throw it away. Please help me to save my dress.
