ive never had a problem with just doing two tarp zippers. if you make the poly longer then the ground and also the zippers youcan allow youself to actually have your door 3-6inches longer then it needs to be blocking any light (or anything that will truly matter).
that door was sweet but only 30" wide... my doors are 4 foot lol... and the zippers i use now are not light proof but the poly behind them should be.
FWIW the one I use is 36". The link is for reference for people that don't know what a prehung door is.
