I actually used a combination of good ideas from several different video's and written directions .. then made up my own rules
I probably viewed 20 different tutorials (both written and video).
I started by using pillow ticking because it has a straight line in the color weave. Word of caution though ... don't pre-wash the ticking as that can skew the weave. The straight line helped me not only attach the leaders to the rods straight, but also helped me attach the zippered ends. Yes, I wanted zippers.
So I suggest spending a day with google and viewing as many tutorials as you can find, take the best from each and go from there.
