Today I bought some velcro and some blackout curtains and an expanding curtain rod. put the blackout curtains on the rod and the 4 pieces of velcro one on each corner. now the closet is 100% lightproof when I close the door. I was having problems with light shining underneath the door and i usually just rolled up a towel but now it is 100% lightproof and I love it.. to work in the room i just part the curtains.. then close back when done.
