I bought two 6x8 rugs at Home Depot to make an 8x12 meeting space. I plan on putting the carpet on an already carpeted floor. I want to do this to define the space. Have any of you ever done this? I just want to make sure it won't seem odd. Also, do I need to ask the principal before I do this? I wasn't sure if the school would have an issue with me bringing in carpet (kids tripping, etc.). TIA!
