I have on giant area in the back of the classroom that I covered in fabric. Light green on the outsides, polka dotted green on the inside. I would like each section (there are 3) to have border surrounding it. Bought the border-- do you put two lines of border right next to each other? Or overlap them so that they are not HUGE (double width). I am using the same white border for each section, but one will be for RR, one for WW and one for something I haven't decided yet. Anal, silly question, but just wondered if anyone had done this before. Thanks!
