I have been trying in vain to find a site that shows how to make a rolled hem. So far I have had no luck. I found one site that showed pics of a step by step process... But the problem I have with the pics is that in one pics is that in one step they advise you to make a crease using an iron ( I realize that you wouldnt do that with nylon), two steps later they show a pic (that appears to me) to be cutting the material & lopping off that crease... then in a step or two later, it says to fold the material to the crease. It maybe my eyes/bad pics but what appears in the pictures doesnt make sense with what is written.

I just dont want to sew anything incorrectly.
