no you don't have to change it everyday, atleast change it atleast once a month though it's whatever your comfy with (you get ALOT on those rolls, mine is 500ft and i'm only using it to stretch my septum)... you can either add 1 layer at a time.. or when you go to add a layer change the whole thing.
you could... i just don't know how the tape will lay...
