I think the trick is making an "x" with the ribbon and keeping the back of it straight and move the top of the loops around until they are even (the TNT template instructions demonstrate this VERY well!).
I use this method Free HairBow Instructions: hairbow free directions, hair bow business work at home
and hold the bow together with a salon clip while I'm adjusting the loops. Then I use the center of the clip as a sewing guidline and sew it up the middle, wrap it twice, pinch it and sew through the middle one more time.
Ever since I went to this method I have been super happy with the results!! However, if a template is going to come out to make it even easier, I'm getting it!!
