hi all, finally got permission to setup a mini darkroom in one of my spare rooms. i have been lightproofing my room in preparation - i got some thick heavy duty rubble sacks from homebase and have taped them in double layers over my window (bit concerned they may melt in extreme sunshine and set the house on fire) and they are blocking the light perfectly. there is only my door left - im planning on stuffing a towel under the door. light is getting in around the outsides of the door but it doesnt fall onto the paper directly. do you reckon i should still block it up with card/tape or do you think i can get away with it?
