Help? one of my leather moccasin bows came untied?

my left moccasin bow came untied, so I tried tying it again. the result was an ugly, knarled, twisted bow. I talked to several moccasin owners at school. one of them even said "oh, you need a Ph D to ty those! mine always look ugly when I tie them back. nothing like at first. I just decided to wear them that way, sometimes even untied because it bugged me." no one knows. there are lots of yahoo answers questions about tying moccasins, I've seen. I never ever looked closely at them. they don't tie like regular laces! they are leather, thick, short, and two sided. help me, moccasin owners?
