Striped Drapery Panels

Unfortunately I mismeasured for drapes for my son's room, and I cant seem to get any more of the dark grey fabric I I am now adding Kelly Green Stripes to give me my two and half fullness that I want. 
 Now I just have to decide how to do them.  I am leaning towards varying thickness of Kelly Green stripes at the bottom section of the panel.  Hopefully I will turn an error into a nice design detail!  I had originally planed on adding a strip of Kelly Green fabric or ribbon to the inside length of the panels, but I think this will work nicely as well.
