Newbie at least to the art of sewing for ballet.  A friend has asked if I could make a headdress like the one in this YouTube video. I honestly don't know even where to begin other than mad googling which has yielded exactly nothing useful. I don't think I even know what to search properly.

Any advice is much appreciated and welcome!
