Ruffled Nursery Curtain

 I recently made these for a friend's nursery.  she bought some curtains and fabric and just asked me to add some ruffles.  I should say, what I'm about to describe breaks all the sewing rules, but my philosophy is, someone made those up to begin with.

We decided she wanted to have 9 inch ruffles, so I cut each to the width of ten inches b/c I created a seam on both sides.  For the length, the curtains were sixty inches, so I had her get 90 inches (1 1/2 the length is usually what I measure to get enough 'ruffle.'

Instead of sewing and 'pulling' to create the ruffle, I just pinned both edges, pinned the middle, and then created a 'ruffle' as I pinned it down and sewed over that to keep it ruffled.  

To make sure it stayed straight, I drew a line with chalk and just made sure I pinned along the line.
