help build tent in closet please

hey so im tryin to grow 4 plants in my bedroom closet but i wanted to remove the door and continue mylar in some way... Lol dunno if that makes too much sense but i basically want to have a mylar wall with some sort of way in instead of having my door there. Or even to leave the door on and built it tent style behind the door.. Sorry so confused can some one please give me some tips on making a grow room out of my closet

Just... hang a big ass sheet of mylar from the doorframe down to the ground?

k that was my conclusion. I got my friend to go to the store and she asked for mylar and they gave her a huge roll of clear plastic is that the right thing? Thought it was silver lined?
