3 5 3 5 4 11.
As a starting place for the amount of fabric needed for the pleats you can multiply the distance you want the curtain panel to cover by about 2 or 3 depending on how full you want the curtains.
She does a great job describing how to measure how much fabric you will need with the addition of the pleats hems etc.
Press all the pleats flat with an iron creating a 3 inch pleat so that the seam is behind the exact center of the pleat.
Once you have cut your fabric lay the ride side of your drapery fabric down on top of your lining.
For each pleat you need to add 8 inches of fabric.
We decided on 2 pleats so 3 sections of flat fabric.
Pin your pleats so they measure 8 inches and top stitch 8 inches down on both sides of each pleat making sure to back tack at the bottom.
I altered her tutorial just a bit and made my own box pleat curtain.
6 30 it should say lining width face fabric width 6 inches instead of 3 inches.
For my curtain i only wanted 1 pleat.
For the box pleat curtain example the window measured 50.
Return leading edge 4 for sewing the sides.
My board was 42 wide.
So this is how i did my math.
