Ok i would say that first you need patience and i mean lots of patience!
Making bows may look simple but it takes time specially mastering all this new twists and new techniques.You need to keep on practising and pay attention why is one bow coming out good and the others are not.Could it be the lenght? could it be the fold?
What i do is unfold and try try again. Try one style first and after you have mastered it move on to the next. Dont try to make all styles at once, it will take lots of practice!
