Step 6 sew one accordion pleat side to the accordion pleat pockets

fit in the edge of one pocket (which is made of an accordion pleat, so really, its folded on itself, two layers of material) into the crease of one side edge. sew down from the top. this step is hard to explain, its more trial and error. if anyone else can explain it better, please, let me know. or, has a better method at all.
