Okay so I have a tie style ribbon headband for my wedding. I need to know how to keep it from slipping off my head (either forwards or backwards). I have very thick hair that is very smooth and straight so needless to say keeping this on is going to be a chore. My headband is ivory in color and my hair is very dark brown so I don't know about using bobby pins as they would be hidden in my hair but would show on the ribbon. I am wearing my hair half up half down. It was a really expensive piece so I don't want to ruine it by gluing things to it also I would like it to not be permantly attached to something (like a comb) if possible. Any suggestions woudl be very helpful. Thanks.
