We all make them - however-they can be fixed! Find yourself an ink pen like in Michaels or an art store and match the color you need. Be sure to touch it very lightly to see how much the ink runs . Actually, gel pens are best. After fixing it, set the color with a hot iron. Be sure to put a piece of tissue or fabric on top so you don't burn the fabric. You might try it out on a trial piece first. I have done this multiple times and it works! Washes ok, too.
